Hey guys, not exclusive to 12th scale but I have a Hudy automatic tire truer that stopped working at the last race. It will bump the main motor when hitting the switch, but wont do any more than that. I replaced the switch with a new one, it worked twice (10 seconds no load) once back together and is now back to the same. I reached out to Hudy and they are recommending to send it to a dealer. Anyone have experience with this or thoughts if it could be circuit board or motor? There are no "burn" signs on board or bad smells coming from any components.

Thanks
