duo-therm a/c does not start
I just returned from a trip and the whole time I was on 50A shorepower the front A/C worked on the thermostat settings. When I went to leave I turned off my A/Cs before unplugging the cord. After star...

I've been trying to follow this. I believe one of Doug's suggestions was to jump Black to Blue on a relay and see if he compressor runs. Then shut off immediately and report results.
I hate to say this, but really I must ask: Did you restore power once you jumped the terminals?
OK, say you did, and no compressor response. Have you looked for voltage on that Black Wire? A meter between Black and a Neutral, usually White will tell you if you have power to that Control Box, therefore the Relay you're jumping, therefore to the A/C itself.
Some generators have two sections, adding up to their rating. Say 30+20 for a rating of 50. One "side" of the generator could be responsible for the front A/C, the other for the rear. Both "sides" would have their own Breakers, and I suppose, own Transfer Switch terminals and connections.
All this said, DOUG is the expert. Much of what I've said is conjecture based on other things I've worked on, NOT a 50A coach with genset, two A/C, transfer switch... Follow Doug!
