Another Motorcycle Voltage Regulator (FAKE)

Not all motorcycle regulator are created equal. This article will tell you how a fake regulator looks like if dismantled. From the housing you will never tell, but what is inside shall tell the difference between a good and a really bad one. From the time it was handed over to me by a friend to look at it. Even i was not sure it was faked. From this post Voltage regulator you wont see the difference externally, they are almost identical, the weight and the appearance, but.....

Bad regulator
Good working regulator
If they are taken side by side, they are identical. Now let us tear down this fake regulator and compare it to the one i posted before and let us see what was inside.
More photo of the said fake regulator properly filled with epoxy resin. Nice job.. It is time to dismantle you. Using my handy dandy mini blow torch and flat screwdriver,
I stripped an area to get down the bottom of it, but to my surprise, the flat screw driver gets punched down easily and here is what happened. White Sand comes down pouring out of the hole made by the screwdriver.
Another photo of this BEACH filled regulator.

From here, I know already what was inside this fake regulator, I already posted one here fake regulator 4 pin

Digging down what was started

After minutes of heating up the epoxy resin and stripping with the screw driver. Here is what inside. A DIODE, yes a rectifier diode

the half of the diode is left inside, take a closer look

A good working motorcycle regulator must have a board and other components aside from a diode.

There are four wires coming out from this regulator and all wires must not have a continuity if test by a multimeter. The green wire and the pink wire on this fake regulator are connected with each other, to which in a good regulator, are separated to other circuitry.

Closer look. So I advice to take precautionary measure of dealing with such kind by using continuity tester. If not familiar with it then bring someone with you when buying motorcycle part like this from your friendly store..(are they really friendly or just taking away your money).
