When I first got my Contessa, I had issues with the chassis batteries that led to their replacement. While trying to start the main engine, and not having the juice to do so, I did manage to get the generator running, then after "charging" for an hour or so I tried to start the main engine and that shut down the generator. I didn't know then, but soon figured out that the Chassis batteries were toast and the gen would shut down under those conditions. Once those batteries were replaced I had no issues with starting while generating.
