I only have a 30 amp service. I think I see what you are saying, cut off the 50 amp plug of a 50A Male-30A Female dog bone. There should be a ground (green), common (white) and 2 hot wires (red and black). Wire them to the NEMA L14-30 and you are using both windings...
Thanks

Surely though the adapter drops one leg and thus I'm back to using on one leg.
That's probably true but then it's better than pulling 26-28 amps through a receptacle and plug designed for 20 amps. I had to read your post several times to make sure that I understood correctly and that you were not going shoot 240v to the 30 amp plug. It sounds like you have it right.
My adapter test was cut short by a thunderstorm before I could get any real data. The A/C was online along with several other devices with the voltage steady at 105v but I wasn't sure which leg was being measured. When I tried the microwave the voltage dropped to 96v and I discontinued the microwave in short order. The breaker on the generator didn't trip at this point. I decided after 10 minutes to pull the cover off the breaker box to check the voltage on each leg but the generator tripped offline when I turned on the bathroom lights. The storm began shorty after that so I put it all away for later.
I knew from the start that I would be dealing with an unbalanced load and now I'm looking at moving things around to even it out some. Once I do that then I'll run another test to see if the generator can handle the loads better. One thing that I was concerned about was that one winding would not be enough to start the A/C but there doesn't seem to be a problem with that. My A/C btw is 15k btu.
