Arrived in Nashville yesterday afternoon and had run A/C using generator power from Atlanta. Got checked in, moved to the site, turned off A/C, turned off generator then hooked up 30 amp shore power. The A/C would not run - in fact the drivers side of the coach had no electricity but the passenger side did. I dinked around, checking breaker switches, power cord, etc and was finding nothing out of order. Was about ready to throw in the towel when the entire system powered up - so I presume it is the delay switch inside the transfer case (mentioned above by Monacoach) and I'll pull that cover to take a look in there to see what it looks like. Anything specific I should look for inside that box? Any other thoughts on what might have caused this problem?
Not 100 % sure but I do not believe there is any delay with shore power and in your case having half power always leads me to GFIs and or Inverter breakers. Stumps me that your power came back on its own.

The delay switch inside the transfer case on ours is a little circuit board with a tiny little dip switch. Cant miss it.

When we are on the road, we make a point of running the generator for both breaks and lunch. 5-10 or so minutes before approaching a rest stop we'll run the generator and kick in the AC. If it's winter we'll run the heat pump. If you do this frequently while you are on the road, this will help keep your generator in good working condition. Leaving the rest stop, allow the generator to continue running for a few more minutes so as to give it a good 20 to 30 minute run.

If you need to run the generator while parked, disconnect the shore power and run it under a load. I know people that buy brand new motorhomes, drive them to Florida, do work kamping, sit tight for 7 to 8 months and don't run or move anything. Too many lawn clackers, screen rooms etc. in the way I guess.

When we were running out in the South West in the summer (July - August) we ran the generator & coach air all the time along with the dash air. Even then, it was never cool in the rig - just tolerable.

We just got done the fourth or fifth of this year's travels in 100+ temps. Our Fleetwood has thick foam-insulated walls, does pretty well in extreme temperatures.

Our own technique is similar, except that we turn off the generator once underway. Today, westbound in the mid-afternoon, we were on the verge of turning the generator back on, but reached home before it became too uncomfortable.

When we're doing maintenance at home, whether inside or out of the storage building, one unit suffices to keep interior temps cool enough to dash in and out.

Someone mentioned to us that perhaps there is a switch that needs to be changed to allow these to work when using the generator. Any ideas on that one? Also we have never driven the coach in hot weather so don't know if the dash air was working properly.
Look at the generator itself and see if there is a breaker switch on it. Sounds like the breaker is turned off. You may also have master power disconnects for the house located somewhere.

I had a similar issue, everything worked at the dealership, 1 month later nothing worked under generator power. Turned off generator and went through all the possiboe scenarios, found the breaker switch on the generator was tripped. Reset the switch and everything worked.

Now if my new to me MH would work as well...
