Info on Electrical for 64 Overlander

[wigwag]

I've had an electrician come and try to figure out why none of these things are working: new FanTastic fan in bath, old fan in kitchen ceiling and the outside light by the door. Fuses are all good... he figured maybe there was a damaged wire SOMEWHERE. I have had a huge mouse problem and think that they could well have chewed things up.
I guess I should have asked first... do these three things all run on the same wire? My schematic is really basic. Do I have to tear my original interior apart to find and repair this?
Thanks loads.

My comments are based on my '67 Caravelle and thus will assume your '64 is similar. Let's start by assuming the fans and lighting are on separate 12v circuits/wiring all originating from the "Uni-Volt" box. The Uni-Volt gets 12v (& 19v for battery charging) from a simple transformer.

Exterior light gets power from the lighting circuit. Difference is that it is feed by 12+ and grounds to the chassis. All other lights are grounded back at the Uni-volt. On my Caravel, the exterior light is feed from the nearest wall sconce (12v positive leg only) fixture through a conventional wiring device (switch).

On my Caravel, all the fans are on one 12v circuit (i.e. vent fan and galley fan). load and ground originate from the Uni-Volt.

It could very well be that a mouse chewed the wires, but start at the Uni-volt (or whatever your trailer may now have) and look for voltage. Go to each fixture/fan and see where you loose voltage. The wiring is all daisy-chained from fixture to fixture.

I posted some Overlander factory wiring diagrams on this forum last year that might help.

Thanks to you both. This is really helpful.

Some times the fuse is good but the clips that hold it are not tight or are corroded, I would temporally by pass the fuses one at a time. And go from there

Can you post pics of the fuse panel?

I wish I could but my Airstream is 1500 miles away from me right now, and may be covered in about ten feet of snow!
