Evening guys
I suddenly have no 12 volt power to the inside of my fifth wheel. If I run the geni everything works. Switch of the geni and nothing no heater fridge or lights. Plenty of power in the battery. Any suggestions please

On our 5th wheel there's a couple of fuses that are to protect against reverse battery connection, they're in the main fuse board along with the 120v breakers, ours blew once & I'm not sure why. It resulted in no battery power.
The main power from the battery may also go through a thermal protector, these normally should reset, but can go bad & fail.
