I have a bike with a green pedel rear hub motor and kt36/48zwsrm-gp01f7 controller. Got it used not working. Said the hub motor is bad. Battery charges, display controller functions, but wiring to the motor controller is questionable as two wire things plug into 3 wire things etc. no signs of burning in the kt controller. Questions: I’d like a pin diagram for the motor connection (round plug). I have a ebike tester off Amazon but it doesn’t support this connector. I have other test equipment available too. Thought I’d verify the status of the motor first if I can. I have no overall wiring diagram or even user manual. Alternative approach : is there a shop in Orange County CA area that is familiar with this setup and maybe sells parts?
