Hey guys, I’m trying to swap out inverters on 1999 monoco executive, upgrading old xantrax 3012 to the new xantrax 3012, was hoping it was going to be easier with same brand, we moved it out of the spot it was mounted under bathroom storage because evidently it had been leaking water from grey line for a long time and finally it got wet enough to stop it from working, I have a problem now that I can’t figure out, it works as should for short time then it works partially, fridge runs and cools but no interior light, maintainer on battery stops working, tried running extra ground from battery to frame, reset inverter and it works for short time again then goes back to partial again, any suggestions or comments would be appreciated
