Question are you on shore power
Or generator power?
All over head lighting quit
Or just some of it
Our 96 Safari, has 120vac lighting in kitchen and dining and incandescent wall sconces which used to have 60w light bulbs in them,
Two 40w fluorescent tubes for the kitchen work area
Center line ceiling lights are 12vdc
The 120v lighting is all on the inverter output circuit
If you are on generator ... reset both circuit breakers on the generator
