While riding our Sur Ron (only 7 months old) the throttle quit working. I was told to check power to throttle, if power to throttle then check power when throtle is twisted to see if throttle is bad. I have checked the power to throttle and there is none which indicates its not the throttle according to what I have found. How do I check the controller? I do not want to buy a new one if I dont know for sure its bad. Any other ideas or thoughts appreciated.
