Hi,

I've had problem after re-assembling my ebike. No action from the throttle, looked inside the controller the LED was flashing 6 times.

I've found info that tells me 6 flashes is a problem with one of the phases. I tested the phases, one of them had a short to ground. So there were 3 FETs on the negative phase (18FET controller). I've just replaced those FETs, however, the problem is still there. There is still a short to ground on that phase.

Is the controller toast?

Thanks in advance
