Any guesses on what the missing labels are for? Specifically “F” that is powered off. Tried everything and can’t seem to figure it out. Thanks in advance
G water heater
K washer/dryer option
My guess is CONVERTER.
It takes the 120V AC power and converts to 12V DC for lights and such. Reason you did not see anything go out is that when the converter goes off, the battery supplies the DC loads.
You will see something go off…eventually.
Apologies for stating the obvious, but I’d guess there’s a manual for your camper floating around the internet somewhere. I was able to find a PDF of my 1998 trailer with some googling which included schematics for all possible accessories.
