E bike kit diagnostics
About a year ago I converted my Easy Racer recumbent to an E bike with a kit from China. It has now died, and of course my Chinese vendor has vanished. I need some help with diagnostics and buying whatever replacement parts are necessary to get it going again.
I have a 20 amp hour lithium-ion battery with 50+ volts coming out of the associated BMS. The the 1000 W motor is integrated into the back wheel. The thing was running really well, like it would cruise at 45. It cut out temporarily a couple times then died totally. I have no power to the headlight, key switch, horn, throttle lever or battery level LEDs. My suspicion is that the problem is in the controller or some of the controlling circuitry on the handlebars, but I don't have a clue about how to go about diagnosing the exact source of the problem.
Though it looks well designed and built, there are no brand names on any of the parts. I will be glad to supply photos and any additional information if that would be helpful.
I would appreciate it if someone could guide me through the diagnostic process or refer me to a vendor who could. I'm in Spokane Washington.
