Ya know, for someone that came here looking for help and information on how to repair their machine and locate parts. THEN spit in the face of people trying to help. Isn't a very friendly thing to do.
I couldn't give 2 shits if you fix this POS now.
Sincerely
An Eastern Kentucky HILLBILLY.
I know it's probably not the most accurate gauge, but the dial on the dash goes up to 400A (in the red) for discharge, but only 100A (in the green) for regen. I'd very much doubt the controller would put out much more than 100A regen even on a high speed downhill run.
