Thanks for the reply.
There are 2 breakers on the generator. A 30 amp and a 20 amp. The 30 amp runs the first compressor in the AC and everything else in the motorhome. The 20 amp breaker runs the second compressor only. I have had the problem occur when nothing else is running but the AC. I don't have the unit here to check, but I think it has in the neighborhood of 1400 hours on it. It does not use an unusual amount of oil and I have not seen it smoke.
Do not overlook the converter is active when you run the generator. They draw generally 7 +/- amps. Depends partly on the state of charge of the batteries. I had the same problem as you and exhaustive testing by a factory electrical engineer determined to many amps were required for the generator output. The converter was a major contributor of the problem.
