Anyone familiar with LCI Ground Controller 2.0 (Electric)

I had a problem with one rea r jack this spring. Lippert sent me a new control board and that took care of the problem. You can get a set of jumpers and jump each jack directly from the battery to check the wiring itself. Lippert had me do this as a part of trouble shooting the problem.

Another suggestion I would make is disconnect the power going to the control board and let it reset itself. Not the control panel but the control board itself.
