Front Panel Lights and Switches Out

[AustinAir]

It is raining here in Austin and I woke this morning to find that my water pump and all the lights and switches in my front panel of my 73 31ft rear bath no longer work. I checked the battery and it is good interior lights and 120v appliances work with Honda generator running. I checked the 12v breakers and fuses in the closet they all appear to be ok.
Any suggestions? Is there a fuse in the front panel? How should I trouble shoot this.
Thanks for all help. I am clueless.

Three possibilties.

There is a fuse behind the panel.

There is also a twelve pin connector at the back.

A bad printed circuit board.

Hi Andy, Get a meter and recheck the breakers and fuses. Looking at them won't always give you a clear picture.

The control panel on my 75 TW has a fuse that is located on the panel side of the 12 pin connector on the 12 volt line. You have a different panel in a different location, but you most likely have a fused line as well.

Are any 12DC appliances working?

I have a similar model and I had a similar problem...
I ended up finding a hard wired fuse which appeared to be factory installed which was bad causing dead 12VDC connections everywhere. The fuse was connected in series to the blue line about 6" in off of the tow connector. I pulled it out and reconnected the blue charge line, and everything worked as it should.

But it sounds like the fuse on the printed circuit board is what is bad if no other DC appliances were affected. So these might help:

Did you check the fuses at the Univolt?
