Ok, I have an old mongoose CX450 bike. I upgraded the battery from the stock 24v SLA to recycled lithium batteries running 36volts. I burnt the stock controller out last year as well as the controller that replaced it. I recently made 1p9s lithium batteries from a chevy volt module and bought a kelly kds36200e controller. I have programmed the kelly controller to specs that fit the bike and upon hooking it up and powering on the battery the motor kicks on. The throttle has no effect, in fact I can have it completely unplugged and voltage is still being sent to the motor. I am pretty confident I have the wiring correct, could the controller be defective? Has anyone else come across this problem? If I cant figure out this controller does anyone one have a better suggestion that I wont end up burning out. Thanks
