I have a 36V LiFePO4 front hub drive setup bought from E-BikeKit in 2010 that I am having a hard time troubleshooting. Battery is fully charged (reads 41V on digital meter!) and the handlebar controller turns on when power button is pressed and indicators light up normally, but wheel motor does nothing at all when thumb throttle is actuated. Hand brake lever switches seem good, they are 3-wire hall effect type. I pulled the motor coil 3-wire connector off (Anderson type) and put a voltmeter across all 3 combinations from the controller and I get nothing (with throttle actuated). The controller has an 8" multi-conductor pigtail ending in a circular 8-pin connector that connects with the handlebar computer (model 709 -maybe made by JueShuai), throttle, and brake switches (outer cable has a molded split to these 4 items). Also a 6 pin (5 wire) Scooter type connector for the motor hall effect sensors.
I've looked all over for obvious wire breaks or bad connectors and found nothing. I don't want to start scrapping off insulations from wires to test more voltages before I get a better handle on how the circuit is supposed to work. The company, E-BikeKit says it is too old and they have no schematics or useful help on the phone. Again, the motor cannot be made to turn or even make a noise. Any help would be appreciated!
PS: The controller also has 2 small single connector wires and a 3-wire connector coming out of it that are un-hooked - look like they are extra.
