Both the 20 and 30 circuits come back through the lower conduit and runs to the main breaker box in the coach.

Anyway, your ATS should look and operate very similar, the only difference is you don't need to move your cord. Again, most coaches have the ATS in this area, but not all. Yes when everything is operating as it should, you can run both ACs at once with genny running, that's what's nice with a 50a genny in a 30a coach.

Yes, all the ATS does is route the 30a to the coach regardless of where it's coming from. In your coach, I'm just not sure if that ATS handles the 20a circuit at the same time or if it is handled somewhere else. When you find the ATS and the in and outbound wires, that should be apparent.

Mine does not look like this for certain.

I did get in touch with Fleetwood and they sent a better wiring diagram. From what I can tell from the print and have heard is the 20a should power the front air, the 30a do the rest of the coach. That is definitely not what I experience.

From what Lincolnboy just described with his FW, if you missed seeing or finding that 30a recepticle for the power cord when using genny, that exactly describes the problem you are having. This is also an indication since you are seeing no ATS.

Question
Based on what I am reading in your Coach's Owners Manual, do you by chance have a Intellitec Climate Control center?

If so then that plays a part in controlling some of this

Yes. That is mine.

UPDATE:

I found the problem.

Inside the Onan genset I found the two load wires at the circuit breakers to be reversed. The 20a breaker had the black/yellow wire attached which should have been on the 30a breaker. The black/yellow wire connects to the 10ga coach wire at the 4x4 box in the genset compartment.

Tested and found the front air runs on the 20a breaker, the 30a controls everything else. Just as it was supposed to.

Thanks for all your input everybody, it was a learning experience.

Thanks for the update. Glad you found the problem.

Then I got my Air Conditioners totally reversed with my prior statement. I thought the back one was on the 20 amp but I know it must be the front one, Jeff.

Sorry, I'm gettin old....and CRS Syndrome.....
