Hey everyone,
First off, I wanted to give everyone here a thank you for participating in these forums. It's been such a helpful resource as I tinker on my various contraptions
My issue is that I'm midway through swapping a controller on a old/broken ebike I got for cheap. It's a very standard 36V/500W in-hub setup, so I picked up one of these guys: https://www.ebay.com/itm/182583980617
I connected up the the battery, lock/ignition, hall effect, motor, and throttle wires. Plugged in the battery, and: Nada. No movement at all. Just to test, I connected up the self-learning wires and turned the throttle. No movement, no nothin'. No matter what, I can't get the motor to budge. And, I know the motor is good, because it was working somewhat with the last controller.
Figuring I had the throttle hooked up wrong, I tested the voltage across all of the wires that are meant to hook up to the throttle and LED display. Based on my (admittedly limited) knowledge of throttles, I would have expected to find a 4.2v signal, but I didn't-- I could only find a 0.8v signal. The signal is very steady, though, so I don't suspect component failure.
Here's where I'm stuck: I don't know where to go from here. Test more wires? Buy a new controller? If anyone here has experience with troubleshooting controllers, I would love some ideas!
