Condenser fan Wiring

1999 National Tradewinds 7371

I'm looking for information about the wiring of the dash AC condenser fan. I have traced the 12v power lead back to the condenser fan relay (the relay is working) The 12v feed to the relay is not hot under any circumstances and I cannot trace that lead back to any fused or other power source (it disappears behind the dash panel in a mass of wiring harness that I cannot get to even with the dash opened up). Does anyone know where that power lead originates? I cannot find any open fuses and I do not have a [COLOR=#0072BC ! important][COLOR=#0072BC ! important]wiring [COLOR=#0072BC ! important]diagram[/COLOR][/COLOR][/COLOR] for that circuit. The Evans Tempcon wiring diagram only shows that lead coming from a 25 amp fused battery source.

Starduster -

FWIW, I have a schematic for the dash air on my Camelot. Can't say how close it would be to the one in your coach.

It shows the full circuit for the fan and every other electrical component of the system. It's too big to upload as a photo (it's in pdf format, and when I convert it I can't get it small enough for the jpg limit), but if you want a copy, PM me your e-mail and I'll send it along.

Thanks, What year is your Camelot? Do you know if it has an Evans Tempcon dash AC/heat?

Freightliner chassis, right? The chassis builder makes available the power and wiring circuits for the coach maker to connect to. National wired in the A/C for power to whatever Freightliner made available. It will probably be in one of the Freightliner fuse panels.
