There is a thread on this with a diagram explaining how to set up a separate power source for the rear A/C. I may have printed it so if you cannot find it send me a note and I will see if I still have it.

I have a 2011 Fleetwood Terra class A. It came with 2 ac units on a 30amp platform. The wiring has not been changed (best I can tell) and the 20amp breaker on the generator goes nowhere. I figured this out by removing the metal cover on the 120 volt junction box at the generator. Only the 30 amp lead from the generator is connected to the coach wiring. Then it goes back to the transfer switch and then to the converter and a/c units.

I'm planning on converting the coach to 50amp and upgrading the transfer switch, converter, power plug and associated wire runs.

I've had good luck working both ac units on 30amps from the genny or shore, but have to limit other loads while both are working. I did find out I have a mach 1 and mach 3 power saver units.

I have done the mod to allow running the second ac (the one that should be feeding off the 20 amp breaker on your generator) off a separate 20 amp feed line and it is a real winner. It allows everything in my RV to run all the time without shedding, acts very much like I have a 50 amp feed. However, mine does have the wiring correctly done before the mod.

This thread, while ultimately caused by a different problem probably has some info that will help you as work through diagnosis:

I know that my motor home is a different model but when I bought it I had a similar issue with the a/c's. I found a relay in a metal box under the bed that had been wired around because of a burned diode and resistor on the relay. This is a transfer switch for the generator.
