Motorcycle Charging For HID (full wave conversion)

Installing High Intensity Discharge on a small motorcycle which utilizes the Half Wave charging system will surely have lots of problem when it comes to battery not being charge to the fullest when using HID. This kind of lighting system actually not common to users consume a lot of current from striking the bulb all the way up to where it stabilizes. Even the re-striking from momentarily turning off the HID SYSTEM consumes battery power.

How to compensate for the loss of charge when using HID system?...The answer, by converting the original half wave system into a full wave generator, by altering the winding of the generator inside the crankcase. Looking at the graph of each type below.

By analyzing each of the graph generated by such system, it is very obvious that the full wave 3P when rectified and filtered produces a clean stable dc, that is why many sportsbike and higher displacement machine uses this kind of system. But why do they not used this on smaller bikes like moped and scooters.

Probably because of COST and size of the system. that is why manufacturers, instead relied on the low cost smaller size half wave generator system for carbureted type small machines. We cannot denied the fact, low cost means limited function.

Fuel injected nowadays been incorporated to small bikes like Shogun FI, honda scoopy I, and almost but not all bikes in thailand uses FI uses the three phase system already, so fitting HID system is of no trouble.

But how about to carbureted type?

It can be done, again by changing and converting it to full wave system to generate a more stable dc that will charge the onboard battery and compensate the losses done by the HID system..

FURTHERMORE, never insist the half wave system is enough for hid installation. It is simply not enough even if upgrading to a larger battery capacity.

Disclaimer: I will not held responsible if something goes wrong upon using this conversion without enough knowledge of how the system works, and electrical / technical skills at hand.. BE ADVISED that this modification is not intended for beginner or first time doing it. 

Getting deeper.

Materials needed.

  1. full wave rectifier / regulator (known as R / R too many) like this Full wave regulator 5 wire
  2. soldering iron at least 50-100watts
  3. high temp insulator tube  
  4. OPTIONAL : New crankcase cover gasket (when returning the modified stator and placing the cover back to the engine) 
  5. A digital or analog multimeter (tester too many)

IT is time to rock!!!

Remove the left crankcase cover to gain access on the stator

This stator is from a Suzuki SKYWAVE 125cc, same with shogun FD125XRM and Shogun FL125. There are three wire soldered to its connector base, find the ground by using a mutimeter set to OHMS , connect the black probe to the stator body and red probe to any of the three soldered wires.

The one with the lowest reading of the three is the wire connected directly to ground, with the highest being the end of the winding that will be used later, the last winding will not be used since it is the lighting coil output and will be disregarded all through out the procedure.

Remove the soldered wire to the stator body to FLOAT all windings...(all windings must not touch the body of the stator, full wave will have its own ground via the BRIDGE rectifier of the FULL wave regulator.)

With the ground wire desoldered from its original position, insert the high temperature tube and solder the wire removed from the lighting coil..

FOR SHOGUN its the yellow wire with white strip.

For other brand..please follow your wiring diagram.

what we trying to do here is getting the two end of the stator winding and removing the GROUND from the stator body as shown on the illustration.

when done, first is first..check for continuity and resistance of the whole winding before returning back the cover to ensure everything done is OK!!

Getting ready to wire the regulator from the modified generator

It is very difficult to know if the purchased R/R is a half wave or full wave if check only by appearance although manufacturers uses color coded wire like the photo shown, perhaps by using a diode tester (multimeters) and check every wire, we might be able to distinguished them. As i had told you, there are 4 pin and 5pin full wave available out in the market. If in a way you find such like as shown then probability is they are the same.

By following the color of the wires

  1. Green -- ground
  2. Red    -- to battery positive line
  3. Yellow -- to charging coil (any of the two winding out from the stator)
  4. Pink --- to charging coil (interchangeable with yellow)
  5. Black --- To after ignition key switch

To be sure and safe, for this test use appropriate FUSE  within the positive line going to the battery. its the last line of defense when it comes to possible wrong connection.

Disconnect all loads from the battery, if you have access to another way of supplying your CD ignition then do so..because we have to start the engine to perform TEST. with the help of the multimeter set to DC voltage. tap it to the battery that is connected to the regulator..

GREEN to black probe
RED to red probe

check are reading the battery voltage, on the ignition key and take a look at value, after turning on the key engine OFF, the voltage must not be dropping and stay close to the initial reading.

kick the KICK starter, and stay it at idle, monitor the voltage. READING must now be moving up possible to 13 volts or 14 volts..(depends on the condition of the battery)..

SLOWLY REV the engine while monitoring the voltage reading of the tester.....

as you are revving the engine..voltage must stay close to 15 volts not over 16 volts (overcharging threshold of lead acid battery)..

if all test performed are ok with regulator not to temperature....PUT a load on the battery such as your HID installed...then start the SAME TEST again...

at first when you turn on the High intensity discharge IDLE the voltage must not be dropping and will stay close to 12-13 volts..

if it is, then the system is already working..By looking at the graph above..FULL wave due to the better DC filtering, at idle or low rpm still charging the battery unlike the HALF wave where in the dc is fluctuating.

Full wave also has a better shunting than half wave to the configuration of the rectifying diodes.

NOW u can enjoy your HID system, just make sure you are responsible enough to stoop down the beam for others. happy motoring.

NOTE: since the lighting coil is disconnected and no longer used, all that was connected before will be redirected to the battery being battery operated.

Rey Broncano said...

I'm using a wave100, which i believe it has an AC CDI. If i will convert it to full wave R/R do I need to change the CDI to DC?

Nathaniel Berdan said...

you do not have to convert the ignition from ac to dc..just leave the High Voltage windings ground intact to that ground slug of the generator, Charging coil and high voltage coil do share a common ground. Isolate the charging ground only and float it or remove it from that ground tab...that's it.

Rowell Tabieros said...

where i can find full wave rectifier...

Nathaniel Berdan said...

you can buy it at any of your friendly motorcycle shop, just ask for the full wave type 5 wire voltage regulator.

Rey Broncano said...

just converted my wave100 two days ago. Full wave RR is really working great..

Nathaniel Berdan said...

glad it works for you, share it to others so that they can enjoy their High Intensity Discharge installed on the motorcycles.

jeff189 said...

Sir Nathaniel Berdan pwede po buh ako mg DUAL HID sa skydrive ko? ano po dapat ko gawin sa charging system papalitan ko buh r/r ko to fast charging 4 pin lang po ang stock r/r. need your advice..
Thank you..

Nathaniel Berdan said...

convert your charging system to full wave then use 7aH battery instead of your existing 4ah battery.

victor apas said...

..paano po ba to gawin sa honda xrm125-DS?

Thiago Ken Fuzita said...

Thanks to this excellent explanation could install HID on my scooter.
I made a video hope it helps someone.
Thank you.

Nathaniel Berdan said...

very pleased to know it worked for you, kindly share to others within your country for them to experience the greatness of modifying the stator for HID installation problem free. Thanks for the VIDEO too, and if u do not mind will add your video to this site

nhark alajid said...

sir,pwd po ba ko mag fullwave kahit hindi nka HID?para lang nman sa battery charging..
tnx...goody of cebu

Nathaniel Berdan said...

yes you can but be adviseable that doing this full wave modification, your stator driven headlight and tail light must be converted to battery source.

nhark alajid said...

salamat po sa reply sir,,last question po,,
saan po e tap ang tachometer..

Charles Datingaling said...

Sir ang raider 150 po ba eh half wave pa din tulad ng shogun 125? Plano kac nmin convert sa EFI yun raidet150 eh. Thanks po

Nathaniel Berdan said...

half wave, and if you are planning to convert it to an EFi then full wave is not enough, A 3 phase stator is needed to have a clean DC for the system.

Sir baka defective yung R/R na nabili mo. Pwede ka rin gumamit ng 4-wire R/R, which is currently yun ang ginagamit ko sa wave 100.

Nathaniel Berdan said...

it is either a fake regulator that consist of DIODE only in the inside he bought.

psyrah canete said...

sir magandang gabi po,tanong ko lng sir po sir kng paano mgconvert ng lights from source coil drive into battery drive,teach na mn sir oh..salamat..

psyrah canete said...

sir gud pm po,paano bah mgconvert into battery drive sa brake lights?ngtry po ako,ielaw na mn yong tail light..egusto ko yong brake light lng po sir..?sana matulongan mo ako dito sir..

loveIt said...

sir nathaniel iba pa po ba yun full wave conversion sa battery driven source? i have a 5pin rectifier kabit ko po sana sa 4 pin panu po ba sir?

FeedBack said...

gud evening boss, may similarity ba wiring nito sa mio? salamat po

jayson john sagorio said...

hi there, is this full wave conversion will be apply to dt 125 cdi type 1983 stator? if yes, how to do it?

jayson john sagorio said...

oh, by the way how about the R/R if ever the conversion applicable?

Nathaniel Berdan said...

@jayson, Is your DT125 the LC version..there are too many DT125 version

jayson john sagorio said...

i dont really know if it is lc, but the stator type is separate 2 coils for light and ac current..

jayson john sagorio said...

and no radiator,,by the it is 6v current....

Nicholas Maspara said...

bro Nathan thank you so much for this wonderful idea.

Antoine shane said...

Wow you have provided step by step process of Installing High Intensity Discharge. It helped me a lot, thanks for sharing dear!! Well I am looking to purchase Honda generator eu3000is, could your provide some tips to select the best one.

LeD MasTeR said...

hello there nathan ?

sorry for bad english. im from indonesia.

iam talking about the scr ? what the type of scr to make this regulator?

i have BT 151 SCR it can't place this or not,can't you explain more about SCR you make this regulator ?

and then the PNP transistor for this schematic, any pnp transistor it can't place with type like S8550 or BC327 ?

please answer my question for the complete schematic items.

Thank you

Nathaniel Berdan said...

Hello Led Master,
The schematic of the full wave regulator can be found here

yes you can use the BT151 SCR 500 or 600 and with the PNP transistor, it is 2L SMD code..which is as far as i am concern is part number 2n3906

LeD MasTeR said...

hello there again nathan !!

and the resistor type is 1/4W or 1/2W ?

but iam only have 1/4W resistor. then i replace for 3.2K resistor with 3.3K resistor . such hard to buy the rate like 3.2K resistor ? can't it be replace or not ?

and the rectifier like schematic said MB254 ? but i have only rectifier 25Ampere but i don't know the maximum voltage !

so iam try so hard to make this schematic . so Thank You for sharing your knowledge !!

My motorcycle is Honda Wavedash110. in indonesia call Blade110.

Nathaniel Berdan said...

LedMaster, resistor can be 1/4 watts, even those SMD type can be use. MB254 is a 25A 400V bridge of diodes, so you are at the right track.

LeD MasTeR said...

hi hello nathan . i'have question about the scr positioning ?

there 2 phase alternator can use for recharge.

1 . ex ground

2 . charging coil

if any wire from 2 charging coil from ground or from charging. it can't be swap or not ? maybe the yellow goto ex ground and pink goto charging ?

in my problem scr BT 151 they burn after 10 minutes riding. i'dont use the heatsink for this circuit ?

but this my schematic would you be correction for it ?

maybe you found right for ex ground or charging . im confuse about this .

check this ""

thanks before. please post this image again for correction for positioning ex ground and charging coil ?

Nathaniel Berdan said...

LedMazter, question? Did you modified your stator before making this circuit and put it on your Blade 110. Remember that the regulator is for full wave converted stator, and not applicable to OEM or stock stator.

LeD MasTeR said...

sorry for bothering again ? he he ...

for the detailed for my stator . the ground and email wire that connect to the ground of stator, i remove it with solder , then iam connect to the new wire go out what is connect to 2nd charging , 1st charging cable is white ?

but i leave the yellow one wire that connect to stator .

the new wire out from ex wire iam connect to the new regulator full wave . then why my scr is hot and bridge rectifier hot to ?

maybe my problem is the tab lamp that connect to stator, but i leave it not connect anything... maybe that cause the scr hot ?

thanks again nathan i appreciate your schematic .

i found new circuit for full wave regulator . check this

Nathaniel Berdan said...

LedMazter, do not connect anything on Yellow wire or lighting coil wire..if you do then you are grounding the stator back..

only 2 wire will be use.

The stator must not have any connection to ground...

(test the two wire that comes out of your stator with Resistance tester, connect positive probe to any of the two wire, the negative to any metal of the engine. You should not get any reading..again NO VALUE)

Nicholas Maspara said...

bro nathan pls help me . for XRM125 stock regulator wires are WHITE from stator/YELLOW to light/GREEN ground/RED ignition sw. if i will use 5 wires regulator to convert it to fullwave what is the proper connection? pls need your help.
thank you bro

Nathaniel Berdan said...

Nicholas Maspara, you have to open the left crankcase to access the stator,

the green wire will be removed from the ground slug..(see this link

(kailangang maalis ang ground winding sa stator kung san naka kunekta ang green make it a float yung dulo ng winding na yon ka magdudugtong ng wire palabas..or. un solder the yellow wire at i kunekta sa winding na inalis mo sa ground slug..)

yellow wire for lighting will not be used anymore para sa mga ilaw..lahat ng ilaw..kunektado na dapat sa baterya..(battery operated na lahat)..

NOTE: if u are still confuse with the procedure, u can visit my garage anytime and will do it for you in less time)

Nicholas Maspara said...

thank you bro but im here in bacolod city...what i mean is ,if im using a 5 wires R/R (red,black,yellow,orange,green) na R/R ang green(ground) hindi na magagamit? kasi tatangalin natin ang ground sa stator connect natin sa dulo ng winding? tama ba bro? kasi apat lang na wire came out from the stator while we using a 5 wires R/R .
gusto ko nang mag convert naka HID ako need your help, thanks

Nathaniel Berdan said...

Just for you..TATAGALUGIN ko..

ang kulay ng RR mo na limang wire ay
pink or orange

red ay to positive ng baterya
black ay sa ignition switch mo (after the ON state or yung kuneksyon na pag nag bukas ka ng ignition mo ikakabit)
yellow ay sa stator na DINUKTOR
pink or orange ay sa stator din..(yellow at pink pwedeng kahit san sa stator)
at green ay ground..ground ng baterya..or ground ng buong bakal ng motor mo.

malilito ka kase inuuna mo ang regulator..wala ka papakialaman stator ka mag concentrate. ngayon..alam ko nalilito ka sa stator mo kung paano mo aalisin ang grong nung winding...

IHIHIWALAY mo yon sa bakal ng stator at iaangat at dudugtungan mo ng wire sya mong magsisilbing kabitan nung pink or yellow wire ng RR...(clear na ba..o hindi pa)

Nathaniel Berdan said...

To make CLEAR things here..once you did not float the ground connection of the winding from the stator ground tab


be sure you are aware of what you are doing for this modification is simply not for NAGMAMARUNONG lang..have a qualified electrician with you..NEWBIES...Thank you very much!!!

i am not responsible for any damage you have done in case you did it wrongly.

Zandro Narvaza said...

Sir tanong lang sana ako if di ba to nakakaovercharge ng battery, napapansin ko na at low revs (di ako speed freak) di nahahabol ng charge lalong humihina ang battery

Nicholas Maspara said...

got it bro, thanks nalilito ako sa regulator kasi ang stock 4 wires , 5 ang ipapalit ..
thanks bro thanks.

Nicholas Maspara said...

gawa na bro thanks ganda ....request kita sa fb by motomaniac

Matias Borquez-Pratx said...


I need to Update my Stator 6 Poles AC to Full wave DC) from my Vespa S 50 2007.

I have Many wires :-(

Red ( external with generator coil)

How to Update this stator in Full Wave DC ?

Thank you

Nathaniel Berdan said...

Hi Matias, is your S 50 vespa 2 stroke, i am not actually familiar with italian scoots, but nonetheless i am trying to look for at least a visual photo of your stator all thru the internet.

Matias Borquez-Pratx said...

Hello Nathaniel,

Thank you very much for your reply and your HELP !

Normally for Full wave DC i need 5 wires : 2 yellow + White + Red + Green.. that's Right ?

Please see this 3 pictures of the REAL stator of my Vespa S 50.

Maybe you a little solution for me ... ?

Thank you again.

Matias Borquez-Pratx said...

i send to you the wiring diagram of the Vespa

And the new Regulator/Rectifier Podtronics FULL DC BGM6698 (This remplace the older)

Thank you :-)

Nathaniel Berdan said...

hello again sir Matias, first analysis, indeed you have 6 wires coming out from the stator area.

red--this is the wire from the pick up coil, leave it intact.

white--this is your high voltage exciter coil for your ignition and definitely your cdi is an AC-CDI.

From the wiring diagram, hopefully it is intended for your vespa and what was written there goes to such item.

you have an oil check device installed on your regulator as well as the flasher unit for your signal light, so the stock regulator will remain, but then the other 4 color wires left is what make me very confuse.

Matias, is it possible to check with a Continuity tester between pin 1 and pin 2 (both gray color wire on the regulator if they are connected) pin 2 goes to your lighting..this wire will be omitted after the conversion.

the BLUE wire is what really make my head blown away, why in the world an AC is connected directly to your on board BATTERY?..

Can you kindly check the wire that is connected to the ground tab..(body ground of the stator? before we proceed. Thank you very much.

Matias Borquez-Pratx said...

Hello Nathaniel,

Thank you again .. so sorry i'm NEWBIE ! :-( :-( .. and sorry for my english)

SO ... See this new picture (Take in the manual Vespa S) You have all Colors wires for each connector

- In the middle image (MAGNETO FLYWHEEL CONNECTOR) the number 4 the color wire is GREY (NOT YELLOW-BLUE)

- The Ground in the Vespa Touch the chassis... The Ground in the stator is (i believe) in the body of the stator plate.

Thank you

Matias Borquez-Pratx said...

probably this picture helps you


Nathaniel Berdan said...

Hi again Sir Matias,

sorry for the late reply. Your vespa stator seems to have a common ground on all of the windings there, and may not be able to convert it for full wave, and at this time I am no help to you. I am trying to isolate the charging coil via all of your photo link attachment but it seems visualization is not enough. I need to have to get a hands-on job for a vespa stator to help you. So sorry mate.

jayson john sagorio said...

thank it work for my raider j110. now i am satisfied with the charging,,..

Matias Borquez-Pratx said...

Thank you for your reply :-)

If this is not possible ... I'll connect the HID from the battery.

Last little question ... (for last solution)

Exists a solution in my AC Circuit to have a smooth lights (Ultra Bright) in Headlight and Tail Light, instrumental panel and turn signal? (To have the same voltage in all lights all the time)

Because all the lights of the Vespa is not so bright When The bike running at low speed.


Mark Ian Lim said...

Good day mr nathaniel
I ask If possible the fullwave to mio sporty amore?and if possible and already install . I ask if the battery will not over charge because if day time no lights will use.. thank you

Stavros Bxs said...

Hello i have a honda wave125i efi,can i do this fullwave?and do i have to buy something?
Thank you very much

Nathaniel Berdan said...

Good day to all of you.

Sir Matias, your headlight, turn signal, instrument and tail lights all are powered by different AC coming out from the stator, and will only be bright when the vespa is at revs. If we are unable to convert it to full wave like the way I see it visually, redirecting all of those lights to the battery and adding HID to the system will surely just discharge it faster creating serious problem. if only Sir you are in my country, I will definitely will try to convert it personally for your needs

Mark Ian Lim if you will just follow what is written within the article of all the procedure with the testing after the conversion is done. It will not overcharge the battery.

Stabros bxs Did I saw EFI? we all know EFI needs a clean DC for it to function normally, and that is 3 phase full wave, Honda wave EFI as far as I have known was already using the 11 pole stator in a 3 phase manner so no need to downgrade it to full wave single phase.

Mark Ian Lim said...

Thank you mr. Nathaniel.. this article is very usefull... last question mr. Nathaniel, I can use any fullwave r/r 4pin or 5pin? Thanks again..

Nathaniel Berdan said...

Mark Ian Lim either 4 pin or 5 pin as long as it is a TRUE full wave regulator. 4 pin full wave regulator is almost exactly like the half wave regulator by external comparison, that is why I recommend the 5 pin or 5 wire type when buying it at your friendly motorcycle accessory store.

Stavros Bxs said...

I don't know but here in greece the honda innova (wave) is with carburator and the new are with injection (efi)..
But i can't install xenon or led lamp as headlight because the lights flickering and as i give throttle the lights get brighter..also if the bike is not running the lights are off..

Mark Ian Lim said...

Thank you mr. Nathaniel..Good health and more power.

Nathaniel Berdan said...

Stabros bxs Honda Innova 125 has two variant. Carb type which uses the single phase half wave electrical system and the EFI version which uses the 11 poles 3 phase full wave electrical system.

single phase electrical system lighting flickers and brightens as you rev the engine. The light is powered by AC not DC.

3 phase full wave on the other hand, all lights are connected to the battery and they are all DC.

Mark Ian Lim said...

One more question mr. Nathaniel I can use my stock r/r by rearrange the wire to my stator of mio amore?to become fullwave stator only. The 3 wire white yellow and black from my stator instead I disoldered the yellow and place into the black position and black wire is removing.. I ask if I can do this senario the black wire pin change into yellow pin. And the yellow pin from stator I will cut only..less hussel but only wiring can confuse only If other they dont know. Please correct me if im wrong..

Nathaniel Berdan said...

Mark answer is NO. If you will not remove the ground of the winding from the metal body of the stator, the winding is still half wave. Please read the article again thank you.

Stavros Bxs said...

Yes my bike is honda wave 125 but here in greece both carb and efi editions use the same DC.. So it has single phase electrical system lighting flickers and brightens as you rev the engine. The light is powered by AC not DC. So what i have to do to make it DC and install HID?do i have to buy anything?

Mark Ian Lim said...

Ok sr. Thank you...

Nathaniel Berdan said...

Stabros bsx you have to convert the stator to full wave by removing the winding connection to the ground tab body of the stator.

green wire is the ground wire for honda, look for where it was soldered, and the winding near it should be the one to be remove and a wire to be added that routes outside the case.

as of now you have three wires coming out
Blue with yellow line--pulser coil out
White is charging which will be intact.

try following the posted video above.

then,purchase a full wave regulator for motorcycle which will be compose of 4 wires namely 2 yellow or 2 white, 1 red and 1 black..

Stavros Bxs said...

Hello again my friend,this is has 6 pin!

Stavros Bxs said...

And this is my stator..

estregan said...

Hi, yan po diagram ng lml star 200 4t ko. May idea na po ako how to modify my stator, pa
patulong na lang po pano wiring sa 5 pin rr.


Nathaniel Berdan said...

Stabros bsx hello again friend, your stator connector is 4 pin and your regulator is 6 pin, your wiring diagram shows 4 pin for the regulator, the stator shows it is indeed a single phase half wave system. green is the ground wire, whereas one end of the windings is connected to the metal body of the stator.

Estregan good day to you sir, your motorcycle is an AC-CDI with external high voltage exciter coil..the green wire represents it. The black wire is your ground, you have to open the stator side and access the windings.One end of that winding is connected near that black wire and you need to desolder it leaving the black wire connected to the solder lug. After that you have to either extend the removed winding with a WIRE o the outside of the crankcase..You'll have then the BLUE wire plus the wire you placed outside as the TWO WIRE for the full wave regulator..(your existing regulator will be discarded and be replaced by a 4 WIRE full wave regulator)

estregan said...

Yes, got your instructions and pretty much know what to with the stator windings.

What i want to know is how do i connect my purchased 5 pin regulator /rectifier. Thanks

Nathaniel Berdan said...

Estregan here is the link if the full wave you purchase represents the same color of wire

estregan said...

Hi Nathaniel, I already saw the diagram. However, I am not sure how to apply it to the diagram of my scooter. Could you please tell me which color wire from the rr connects to which color wire in my diagram?

Nathaniel Berdan said...

Estregan hello again sir, after completing the removal of the ground winding and putting a wire that goes outside..

check this link.

Thank you.

estregan said...

Thanks, this confirms how i plan to do it. Will report back what happens after i try it.

subcode said...


hello po.. ahm, meron po bang other way na ma full wave using the full wave r/r without modifyng the stator coil?

Adrian Borboran said...

sir tga nathaniel pwede po b ako mg pa fullwave sayu ng raider ko my hid projector kasi ako ts tinggl ko sxa ksi lks mlwbat panu ko po kyu mcocontact para mkpg pgwa ako sa inyo

Nathaniel Berdan said...

subcode there is no other way..u have to open that left side crankcase..(pag hindi mo tinanggal ang ground nung winding, grounded pa din ang stator, pag nag ikaw ay nag full wave...walang winding na nakadikit san man sa body ground..)

Adrian email me your contact number, click ABOUT above and select CONTACT ME

Please do not leave any number here thank you.

subcode said...


ahh ganun po ba. kasi po sa pag kakaintindi ko sa diagram above, yung yellow wire eh dun din kinonek sa ground taz pinutol lng yung ground. so yung idea ko eh putulin ko nlng yung lahat nang ground wire na connected sa chassis den yung yellow wire ehh putil din at i connect sa chassis.. paki explain po kung hindi pwede idea ko po.. thanks..

Nathaniel Berdan said...

subcode ang half wave system...grounded ang isang dulo ng madaling salita, yun na ang pinaka ground mo..

sa full wave naman walang anumang dulo ng winding ang kunektado sa ground..ang ground ay mang gagaling na sa regulator mo.

ang yellow wire ay ilustrasyon lamang na pwede mo gamiting wire kung ayaw mo mag dagdag pa ng wire dahil sa full wave useless na ang yellow wire at wala na ito pwedeng KABITAN..

doing so...may UUSOK surebol yon..

alam ko ang iniisip mo...kukunin mo ang yellow at di mo aalisin ang ground..TRY mo..hanap ka nga lang ng FIRE EXTINGUISHER..dahil di ako liable sa pagusok o pag apoy ng motor mo

Homer H. Camposo, Jr. said...

Sir Nathaniel, if mag convert po ng full wave para pang charging lang at hindi naka HID diba advise nyo is e convert ang stator driven headlight and tail light to battery source. Ok lang po ba kung mag higher wattage ako ng headlight like 55 or 60 watts instead na 35 watts lang? kakayanin po ba ng system. need ko din ba mag change ng higher amp na battery, mga ilang amp kya ang pwede? TIA.

Nathaniel Berdan said...

Homer converting to full wave does not mean mainly for the purpose of High Intensity Discharge lighting system fitted in a motorcycle. It can also be applicable to thise who just need an extra boost on charging during engine idle. We all know when the conversion is done, all lights will be directly driven by your battery, and thus will add additional load in it. Just make sure the outgoing current being thrown by the battery on those lights will not be less than the current thrown in by the conversion of the entire charging system, Use AMMETER to check and for the process of how to connect, feel free to use the ALL FREE GOOGLE SEARCH.

Nathan Liwanag said...

good day sir, i convert a honda wave 125 from my friend ,i follow everything but something go wrong all wire get melted ,i'm wondering about it's stator coil, the resistance is twice as my wave 100 it reads around 2.5 ohms is that ok sir ,i already converted the stator to fullwave and i use a 5wire rectifier,thank you in advance sir for giving a comment,

Nathaniel Berdan said...

Nathan i am sure your purchased regulator is FAKE, that is why all wire got melted.

Marc Hubert de Guzman said...

gudpm sir!

is this applicable to yamaha mio MX125??

Nicholas Maspara said...

gudpm nath, using an ohm meter , how do we know (test) that the RR is fake or not?
any testing procedure for the RR before we buy?
thank you very much

estregan said...

Hi, just want to report back that my full wave conversion for my LML was successfull, thanks to Nathan for being very helpful. Cheers!

Na Na said...


I have honda scoopy classic scooter(carbutetor, not eletronic fuel injected). I DIY installed 4 hi-LED foglamps , 6 LED underglows, Tri-LED headlight, LED light instruments, hi-LED parking & brake lights, and third LED parking & parking lights in the givi box... I also replaced the horn to a more classic tone.

ISSUE: Whenever I turned on all lights, horn is weak and even stops working. Its working fine if fog lamps and headlight are turned off. Im really confused due to all lights are LED and have low wattages. All LED lights arent dim if all turned on, only the horn weakens or stops. All systems are converted to battery driven. Is the ampere of my battery not enough? What shall I do?

Some adviced me to get a so called "fast charger"... Others told me to remove or disconnect a certain wire in the rectifier/regulator to gain faster recharging(is this true? )... I dont know how, Im no mechanic nor a technician, just know the basics.

Anyone, please HELP!

Good day sir! Is there a possible way to convert raider 150 into a 3-phase full wave system? Tnx and more power! 09334059722

Nathaniel Berdan said...

Na Na Is your charging system still at the stock or original configuration? If YES, then there is your answer to the problem. Kindly read all possible article on this site about motorcycle charging.

chino possible but what is your primarily intention? Full waving the raider r150 is enough that is if you are planning or have plans on converting your entire ignition to EFI system then the 3 phase system is mandatory..

chino said...

Good day Sir Nathan. Ask ko lang po, after getting the two ends of the stator ( which is the ex-ground and the original charging coil), does the center tab can still be used for additional charging purposes? If so, does it require a certain type of R/R? Tnx. 4 reply!

Nathaniel Berdan said...

chino the answer is NO, since you omitted the ground, center tap which is the yellow wire is already unusable.

Roy said...

good day sir nath! plano ko rin pong i-full wave ang kawasaki fury ko. mukhang madali lang naman yung sa stator, so ang question ko nalang po ay kung paano malalaman kung full wave o half wave ang R/R? pag 5 wires ba yung R/R sure na full wave sya? yun rusi na motor ng kaibigan ko 5 wires yung stock R/R nya. yun nalang gagayahin kong model ng R/R kung sure na full wave sya.

Nathaniel Berdan said...

just ask for a full wave regulator 5 pin at your nearby local shop. If they do not know that then the shop is not selling any.

FYI, there is no such thing as "madali" for even us who built and sell full wave regulator do mistake for not all stator are not created equal thus every motor have different regulator.

Roy said...

hindi naman po sa pagmamayabang kung sinabi kong mukhang madali. pinanood ko po yung posted video nyo at kinilatis ko na rin po kasi yung wirings ng stator ko. kahit papano rin po ay marunong naman po ako sa electricals kaya ko nasabi yun. but anyway salamat po sa paalala. pag hindi na limited budget ko gagawin ko tong guide nyo.

salamat po sa tutorials na ito sir!

good day again sir nath! may itatanong pa po pala ako. kasi di po ba center tap ang stator dito sa tutorial nyo? 1 line for charging, center as body ground and last line for headlight. what if lagyan pareho ng diode yung line 1 and 3 then yun ang papuntang stock half wave rectifier? half wave line 1 + half wave line 2 = full wave. click here for the image

Nathaniel Berdan said...

roy do not be mistaken with the full wave (2 diode) vs full wave bridge (4 diodes)..I know what you are thinking right now in lieu of that center tap winding.

As far as i know, you cannot use the existing stator winding for full wave in either 2 diodes or full bridge unless you float the last end of the winding that is connected to ground..

I never experimented with the 2 diode full wave using the center tap as ground, for i have not seen any circuit with 2 Thyristor connected to the windings of the stator for clamping...

If you have any circuit available, why not share it here..for there are too many visitors all over the world, not only in the Philippines but worldwide viewing this..

The site is not a forum like MCP, but you can post everything you have in mind for others to see, as you do.

Thank you.

Ano color po ba ang dapat tanggalin sa regulator sucket pra mag fastcharging smash 115 at 3LED po ang motor ko...

Roy said...

paps Nath, may nabili akong 5-wire recifier/regulator. color coded naman yung mga wires maliban sa black. as per your post is black pero yung sa akin is red na may white line. bale red, green, yellow, pink tapos yung 5th wire is red with white line. ask ko lang kung full wave ba itong nabili ko? hindi alam nung pinagbilhan ko pero dahil nga sa 5 wires and tama naman color code nung 4 wires kaya sumugal na akong bilhin kahit di ako siguradong full wave. chaka last na tanong na, pwedeng patulong kung may idea ka sa wiring diagram ng stock rectifier ng kawasaki fury kung what wire goes where? tia!

subcode said...

sir, yung rectifier na nasa picture, ganyan din ang stock rectifier nang mga 110 unit nang mga rusi. full wave rectifier kaya? tsaka ang stator nila na 6 poles, instead 4 wires, 5 wires sya at green ang ikalimang wire na nka kabit sa ground. so meaning, pag pinutol ko yun, wla nang bodyground at possible ko ma fullwave ang charging system ko without modifyng the stator itself.. sa tingin nyo po sir? tama kaya na isip ko?

ezekiel herras said...

sir m.circuit ask ko lang po panu po pagconvert ng headlights to dc, ang ginawa ko po kc inalis ko na xa sa yelow wire from stator the i tap it to black wire w/c is acc pero pang pinaandar ko c mc sa stator parin galing ung power kc pgnagmenor humina din ung me nman po panu ko iconvert sa batt ang lights ko..tnx po and more power master.

ezekiel herras said...

sir nathaniel ask ko lang din po, bakit po ung battery ng mc ko pag-inalis ko ung wire sa positive then test ko siya with multimeter para sa continuity tap ko ung lead sa wire na positive then tap ko sa body ng mc ala continuity pero pag kinabit ko na sa batt ung wire, may continuity na nag beep na ung multimeter. anu po ibig sabihin nun? tnx po sa sagot

How to test a regulator rectifier ?

Ian Ray Lagundino said...

sir nathaniel, xrm 125 po ung motor ko, nka hid projector 6000k po ang headlight at may mga LED lights po ako sa front na malalaki, pinagawa ko po ung charging system ko sa electrician samin pinalitan nya yong stock na regulator ng XRM ko sa 5-wire regulator na binili ko sa shop, kaso ngkakaproblema po kasi one time ng overheat yong battery ko at nasira. pinalitan namin yong batery at saka linagyan nya po ng switch connected to regulator na kung gagamit ako ng headlight ko i-on ko yong switch.. kaso po kapag hindi naka on yong switch ko bumabagsak yong charge ng battery ko(11.9 hanggang 11.5v). ano po sa tingin nyo ang problema po? salamat po..

How to fast charges

Meron wire na color white/yellow mula sa stator
Putulin mo un
Then ung yellow/white na isang side (hndi ung galing sa stator) ay itap mo sa color orange (ignition wire un)
Then ung wire n galing sa stator eh itape mo nlng...
Yan ung first trick
Nagets mo po ba bossing?
May nagsabi lang po sakin sir, nag check din ako ng 3 skydrive na naka fast charge at yan din nakita q.. Tama po ba yan bossing? Kahit hindi na palitan ang R/R?

RAM Bow said...

sir nathaniel,
nagawa kona ang fullwave conversion sa stator. bago ko ginawa ito kumakarga pa ang bateri sa pamamagitan ng dissconnected ang yellow wire.
after ko magawa fullwave pati nadin ang fast charge rectifier. parang inuubos ang karga ng baterya. nakikita ko sa volt meter kumakarga next day walang karga ang bateri ?
ang koneksyon sa rectifier sa 5 wires sinundan ko ang stock wires nito at ang black wire sa ignition. thanks

Nathaniel Berdan said...

I guess you did something wrong. Again, as i have been telling all of you before. Not a job of beginners. Check again and make sure your regulator is not a FAKE one.

toto balasote said...

Sir tanong ko lang po kung papano iconvert sa full wave ang suzuki smash 110? ganun din po ba ang gagawin yong kagaya sa video nyo sa youtube? magpapalit din po ba ng rectifier/regulator? Salamat po.

Sir good day sayo (NEWBIE HERE). How about my sniper mx 135, can i apply this fullwave rectifier/regulator? Does my MX single phase or 3-phase? i've got DC-CDI hindi po ba masisira eto if i converted to fullwave? What is the first thing to do? Soory sa dami ng tanong po....gusto ko lng po matuto then apply it to my MX. Salamat po ng marami.....

dane llorera said...

sir san po ba ang shop or garage nyo? baka pwedeng makabisita at makapag pa full wave.. motor ko pala is honda wave 100r.. pde din po ba makuha number nyo sir? salamat po and waiting for your reply..

Vincent Fernandez said...

Pano po iconvert yung stator ng suzuki smash 115 into fullwave? Thanks

cesrep25 said...

Pano po malaman sa mga coil ng stator kung alin ung ground? Kung alin ung lighting coil? Ano po ang madaling paraan para madistinguish ang bawat isa?

Romello Olbes said...

Is this idea work also on my Fury 125 Kawasaki?

Nathaniel Berdan said...


the only best way i know how to know the ground, the lighting coil, and the charging coil of your stator is by using an INDUCTANCE METER..this will ensure that you will get the right coil since the using resistance using Multimeter will be a puzzle for beginners.

Inductance meter is used to determine which coil have the larger inductance that will denote your LIGHTING COIL. Test will be in relation to ground.
