Ooookay, Thank you so much! A search of the PDF manual located the switch, "house battery cut-off switch", and I'll have to verify the other is bay lights. I also have a switch labeled "bay lights" that didn't turn them on. I figured all the bulbs were fried and I needed to put in new bulbs, planned to put in different style LED's.
Pretty sure I've had a monkey in the works, stove, fridge and furnace all work on propane, have 12Vdc & gas. Hot water heater has no 12Vdc, haven't checked gas, works on 120AC. Door switch makes no difference what works in coach that I have found, all lights work, water pump, guages. It''s a good thing my specialty was automotive electrical.
