Help with camper electric jacks!
I need some pretty urgent help with my camper. I went to put down the front set of electric Atwood jacks on my camper this afternoon, and they worked intermittently. They didn't work at all at first, ...

As an EE I am always interested in electrical problems. From looking at the Atwood links posted earlier it does not appear these jacks are the typical Atwood Truck Camper jacks most of us are familiar with which work as Bigfootford described.
Truck camper jacks do not and should not connect in any way to the "frame" of the camper. How could that work as many truck campers have wooden frames. These appear to be jacks designed for attachment to a trailer and therefore a metal frame is available.
A good wiring diagram would really help solve the problem. It's hard to tell but from one of the posted links it appears that a ground wire connects to the jack and two other wires attach to the motor. This will work with a motor with a fixed ground as long as the two wires attached to the motor go to different windings in the motor...power to one turns one way... power to the other turns the other way.
Good luck troubleshooting the problem. Be sure to post when you find the solution.
