Two of the male pins which are normally potted into the contactor fell out and are in the female connector attached to the control wire. Further observation showed that the pin is broken off inside the contactor and only the broken end is in the connector. The pins of right red wire and the middle gray wire are broken; the left red wire is still intact. I had the Port Sanilac Marina techs look at it and they said I needed a new contactor and that would solve my problem? I questioned this as I told them I had jumped the incoming hot wire to the motor power stud and nothing happened. Again I have done the same on car starters to find if I had a bad starter solenoid. They insisted that it was the contactor so we ordered a new contactor which arrived in 2 days.
The technician removed the old contactor and installed the new. To do this he had to remove the nuts from the motor power studs and reattach. As he tightened the nuts I noticed that the studs moved slightly. After it was reassembled we pushed the up and down buttons and again heard the clicks but louder this time since the cover was off, but no action from the motor. I am looking over the motor much aggravated of course and noticed that the right motor stud was up and out of its socket. We wiggled the other studs and they came right out with little effort.
