Have a commercial built Wisper 905e Electric Bike.
A month ago it started to blow the 20amp in the battery pack as soon as you turned it on.
Local electronics store has now eliminated the blowing of fuses.
The problem now, is that you switch the bike on, all is fine until you start to rev. No matter what stage the throttle is, it is blowing Chips IRF1010 Q1 + Q2 within the controller, no matter what load you have on.
Controller is 2008-2009 with black 8x multi pin motor controller plug if that helps.
We have not a clue and are running out of chips. Thanks
