BMW f700GS instrument gauge failure

This BMW F800 adventure  is known for the intermittent and blackout issues, but more often was the blackout non functional unit. There has been many that I repaired and they are all the same may it be brand new or old unit. It has something to do with the battery. If it gets low on charge, highly possible that the panel will stop working so does the defective voltage regulator that induces the non regulated charging method on the battery.

Unit has only 6 pins and you can always power it on the worktable.

PINOUT

1 - CAN BUS communication A
2 - CAN BUS communication B
3 - B+
4 - GND
5 - Alarm (connected to the positive maybe from after IGNITION SWITCH
6 - Not connected
