Hi. I’m trying to figure out why my ebike brushless hub motor won’t spin when I throttle. It seems like the voltages across hall sensors and the throttle are wrong.
The H+, W, V, U, GND pads are for the hall sensor. I get .77 volts to the H+ to ground. I get 1 volt on W, V, or U to ground, even when spinning wheel.
The SD, 4.3v, and GND pads on the left are throttle. There is .66 volts from 4.3v pad to GND. There is 0 volts from SD (which I assume is throttle sensor voltage) even when spinning the throttle.
I don’t know what is going on. I didn’t really do anything to the controller other than take it apart. Maybe something got destroyed by static? I need help!
