We just bought our AS this spring. Our 1977 Trade Wind has 2 deep cycle 12V
batteries powering the 12V
system and I have only been able to get the rear ceiling light/vent combo to work. The forward two ceiling lights don't work. I checked bulbs and they are OK. I thought I would leave it to fix later...
Today I hooked up the 7 pin trailer connector to the truck and the forward lights are now coming on, as is the stove fan???
I thought it didn't matter - that 12V
lights would work by either TV battery or RV battery. Anything I need to be doing differently to get the 12V features to work without having the AS plugged into the tow vehicle?
