I re soldiered the connections on the circuit board for the class system errors I was getting, re installed the unit hooked up the battery turned the key to acc, the controller came on no errors showing sounds great so far but read on , switched it to manual and pushed increase, all the power on the bike went away except to the controller? I have no power to anything else.
what the heck happened?
I checked all the fuses, the main fuse looks ok through the window but it could be bad where I can't see it at.
