Careless mistake on my part. Had Bafang Besst hooked up changing some settings, unplugged the usb cable from my computer, and it just grazed the handle bars. It sparked, and immediately the throttle stopped working, there’s no speed displayed, and as soon as you pedal and the motor kicks in, it throws a speed sensor error on the display. I’m thinking it killed something in the controller, but what about the display? I’ve tried a known good throttle already, but still nothing. Thanks in advance for any insight. Any one know how to check it?

If the USB conects to the serial data lines the display uses to talk tot he controler, then they are probably damaged so that the display and controller can no longer interact. If throttle goes to display first then display sends throttle data to controller, it wouldn't be able to receive it anymore.
