We just bought a 23r and when we plug in at dock the house battery is dead in the am. We want the fridge to run. Anyone know how we should have the controls set to keep the house battery from getting so low? We are doing something wrong.
Have to ask the obvious - are you turning on the battery charger when plugged into shore power? On your main AC Distribution panel it’s the bottom left switch if you don’t have a generator. Has to be on to charge the house batteries which then power all the 12 volt DC systems like the refrigerator, etc...
If you have a generator it’s on the AC Main 2 panel fourth switch from the bottom right
