Ok here's the problem I'm having. First let me tell you what I have a Crystalyte 3540 motor, Infineon 12 MOSFETs 30 to 90V controller and using a 72V 13.5AH battery. This bike has about 2000 miles on it with no issues. Yesterday while riding lost power turned it off and back on and it starting running in reverse without touching the throttle. Turned it off and on again and it started running full speed forward again without throttle applied. Now every time I turn it off and on it keeps wanting to switch directions. Any suggestions on what I should be looking for.?
