My Max-E stopped working suddenly during a charge.
The symptoms are:
When charging the PSU is shorting and going into overheat protect mode whilst "no charge voltage" is displayed on the computer.
When trying to run the motor it just rocks back & forth.
So I see no errors on the display, and the wiring is all correct, intact and tested for continuity. The motor spins freely and it wasn't even hot at the time.
To me this suggests a problem with the FETs, but I can't see any visible damage to any of them so is it a case of replacing them one by one until the fault is found? Or is there a better way to narrow down the fault even further?
