“Appliance selector switch”

[TRAPEZE]

So my new 1985 325 came to my home last night. Some things better than I expected some things worse, but all in all I am pleased, no down right excited.

Now the questions will come.

According to my manual as well as the nomenclature written on the “Appliance selector switch” when running the generator, power is automatically fed to the rear air, and the selector switch may be set on any one of the other appliances. This is not happening. With the generator running, I can select any appliance, and it will run, including the rear air. But the rear air will not run unless I select it. This is even the case when I am on shore power AND with the generator running.

Any tips out there as to where to start looking. Do I have a bad relay somewhere? It is hot down here and I sure would like to run two airs.

Scott,

It sounds like a wiring change was made.?? Is the Generator the one installed by Airstream? I think in 85 they were using a Kohler model. Have you checked your breaker panels? You may just have one in the off position. The breaker that feeds the rear roof air may not be in the main panel with everything else.

I am sure another 325 owner will pipe up. I am sure we can help you to figure it out.

Could be a change in wiring. The AC was renewed two years ago. The generator is a 7kw Kohler that runs strong. It should run the two air’s with little trouble. I will re-check the breakers in the morning. Thank you

Congratuations on your new 1985 325. The fun really begins now.

Part of your new adventure should include going through the coach circuit by circuit. Don't stop with the investigation of the generator problem. Many previous owners when they get to the end of their ownership of a trailer or coach, start doing repairs in a slipshod manner. Be especially mindful of anything that does not look right to you.

It is not the breakers, I tried them this morning.

I have a little history. A friend of mine and his wife picked this motor home up for us and drove it home. In the initial inspection, he viewed both air’s working when plugged into shore power as well as the generator running.

This tells me it is not a rewiring issue. Something happened on the trip home. There must be a relay that isolates the rear air when the generator comes on. Where is it? Am I on the right track?

Scott,

Congrats on the 325 purchase. This is a little off topic.....I'd love some pictures of your 325 for my archives. I only have an exterior photo of a 85 325.

Since your in Florida, we'd love to have you join us at the April 2003 motor home rally. Everyone there last year had a great time.

Even though I have a 1985 345, I'm the web guy. My lack of mechanical skills are legendary in the forum. My big accomplishment is changing the plug wires without blowing up the engine! Don't bring up the hose reel!

P.S. I would have sent you a private message but you don't have a 'PM' button on your posts.

Scott,

You are probly on the right track regarding a relay, but where it is I do not know. If you do not have a service manual, I would suggest getting one as the cost of the manual will save you lots O bucks as you take care of the inevitable problems that come with a classic motorhome. Here is a link to the info:

BTW the Mystic Springs rally was a blast last year, if you can attend it would be great!

I got it!!!
It was a relay in the back curbside of the coach. It just needed a little coaxing and it works fine.
Thank you all for your encouragement. Now on too…..
