The indicator that tells you the jacks are down quit working all of a sudden. It showed that the back two jacks were up all the time. First indications was that the controller was not working -going to put that repair off-. While cleaning out the electric compartment I decided to remove a wire I had run for the lube pump and noticed that some wires had been chewed by something. Repaired the wires and the jack indicators are working now. Sometimes you just get lucky.
