Hooked Up RV Battery Backwards and Now Lippert Ground Control Doesn't Work


No matter what I do auto or manual my jacks won’t come down. I pulled the house batteries two weeks ago to charge them at home and hooked them up backwards. I then hooked them up correctly and everything else works in the Thor daybreak motorhome. Ideas?


Expert Reply:

Pull off the display of your Lippert Ground Control setup and check the fuses you see on the module. Most likely the short fried them and replacing them will get you going again. If they are still good then you'd have a bad module and would need to replace it with the part # LC304136 that you referenced.
