2014 Windsport 34F Electrical issue
First off, we have had constant issues with the electrical system. Just replaced the radio head unit not too long ago and both cabin batteries. Engine battery test good. When I start the RV, I can start the generator and outside lights work fine with engine running. When shutting engine off, the lights start to dim and the lights and generator shut off. Runs fine with engine running. Made sure switch wasn't in store mode and starts back up fine so I know it's not a battery issue. Any advice?
