No need to take a photo they look like these
I do not know this wheel and my guess is your are on your own-have someone look at it who IS GOOD WITHE ELECTRICITY-.You should stay away as you may do more harm than good for it. Over riding the fuze with wire is what you do as a last resort to return from earth orbit(space -cadet) to get back home not fix a wheel.
I meant take a picture of the inside of the foot control for diagnosis
Is there a possibility at all that the motor is shot which is the source of the short?
