I have a gen 1 motor that does not operate. I have gone through all trouble shooting to manually run the motor. I have power at the motor that switches accordingly, but the motor does not do anything. Since it is not a stripped gear, what else could cause it not to operate at all? I am thinking the brushes are broken off. I know you can order them from Rodney Dickman. Just wondering if there is anything else I should check when I open up the motor.
