Every now and then you send a motor out and the owner contacts you that he's having problems, I say send it back....this is the hottest motor I've EVER had returned to me
When/if they "bind", please don't run them, look for smoke and WHY the switch didn't pop on this one I don't know, it never should've gotten this hot.
This shows the importance of having proper crank arm, etc. on a particular application. Binding will cause a motor to run but not turn and they will build some heat.
Turn the KEY off, as long as the key is on, the power to the motor is "Hot" so turning the wiper switch to the "off" position will not save the motor from damage. Turn the key to the "OFF" position
