Darrell,
David gave you excellent advice on troubleshooting the powertech. I have not seen this before on the bird BUT, I have elsewhere. If it were me, I'd do the resistance check David suggestion and if its good, then rewire again. Keep the AC unit that pegs leg 2 OFF and try and turn on a few things so you can get a 20-30 amp load on both legs, then see where you are at with the new wiring. The only other things I can think of for a SWAG would be the bearing is starting to go but there is no way to check that without tearing the head apart. Take a peak at the voltage regulator if you can and see what kind of shape it's in.......
The AC unit that pegs the meter probably has a bad or weak start motor capacitor or the compressor is shot. I'm willing to bet your Blueberry farm on it! hashahahahah-just clowin around! Seriously Have seen this MANY times. Climb up on the top of the bus, remove the AC cover (4 screws). Then remove the metal cover that covers the system and forms the air compartments, about 10-12 sheet metal screws. That starter cap should be on the curb side. You can use your ohm meter to see if it's shorted........ very common deal, maybe its causing the genny to overload leg 2? (SWAG) Please BE CAREFUL up there, Donna always hangs around while I'm up there so she can catch me if I fall! If the cap is bad, you can get what you need locally at any appliance parts supply store on the cheap. They will match it up for you. If the compressor is bad,,,,,,,uuhhhhhhhhh use 2 ac's :-) until you save up for a new one! FWIW I have one that's starting to do exactly that and I Know the cap is good so I do not use it anymore and will replace it.......its on my punch list! It's the middle one so the front and rear AC keep the coach comfortable most of the time.
