Pancake Compressor Power

[Pete Masterson]

I have a Microphor pancake compressor that was installed as an "after
market" upgrade. The wiring seems somewhat jury rigged (it is an OK
but not particularly neat installation). I discovered a "hidden"
switch (well, it was a black plastic switch mounted on the black
metal "box" that the compressor sits on). When I stowed some wheel
chocks, I'd turned off the switch without realizing it, making me
think the compressor had lost power. My compressor doesn't seem to
have any other switch. I assume that it's fused to the rear power
center (the closest one) -- but, of course, the fuse isn't marked in
any useful way.

Look around the compartment with the compressor and see if you can
find a similar switch -- you may have one and it may simply have been
flipped without your realizing it.

Failing that, your best bet would probably be to fish a new wire to
serve the compressor -- there's no telling how it originally may have
been wired if it isn't on the wiring diagrams for your coach.

Be sure to install both a switch and fuse on the new circuit to
facilitate servicing and prevent overloads.
