Gene?

Unfortunately, as the coach was shipped as Transmode, it is anybody's bet what it is. If you tell us who up fitted it, someone can probably make an
informed guess.
My personal bet would be that it is 12V. I have never seen a 14" vent fan that was line powered.

I hope you can tell us if it is a Coachmen, Avion, Norris or even the lost Winny.

99% bet that it's 12V. Will be fused at the house 12V fuse panel, grounded
to the aluminum roof structure.

It was set up by Square D Electric out of Milwaukee they had their display
panels inside and this fan was hooked up to one of them since then all the
panels are gone and I don't have any idea what panel it had been set up to
my best guess is I'm going to have to pull the ceiling there is no house 12
volt fuse panel just the fuse box in the glove box

I'm going to agree with Matt. I have never seen a 120 volt vent fan, but..... it was set up by Square D, and what to they make?

The OEM fan was made by a company called Hammond out of Michigan. The Hammond vent had 2 cranks (front and rear) to open the top. Also that fan had
a center off bat handle switch with one side being full speed and the other going through a resistor for a slower speed.

If this sounds like yours then is 12 volts DC.

If it is wired with romex then is is probably 120 VAC.

Interesting. My '75 transmode was set up as a mobile display and sales vehicle for the Furnas Electric company. It has an extensive amount of BX
wiring. No sign of any 12V wiring in the coach. A/C and electric heat. All coach lighting was 120VAC. No propane. The generator is missing and it
was not a power drawer. The interior was completly lined with carpet. The body has extra horizontal aluminum structure installed with lots of
nutserts installed. The carpet had a larger hole cut in it to allow access to the nutserts.
