Has anyone found what causes this error?
Specifically which component may be causing this trip on GC, GC2 and VR2 controllers.
I am trying to do a board level repair.
All 35v 680uF caps have been replaced
Relay cover popped for inspection: all contacts and coil are working as expected.
Batteries are fine and hold current to board.
All drive FETs test normal.
Can anyone tell me what causes this fault or which PCB components may be triggering it?
