I'm still pretty much a novice here but I have a question regarding my Onan 7000 generator. It seems to start and run fine. However, a few days ago I had it running in order to check the operation of the dual heaters as well as the duel A/C units.
Both heaters came on fine and blew warm...the front A/C compressor kicked on and while not terribly cold, it seemed acceptable. However, when I kicked on the rear A/C unit it lacked a bit of gusto and the generator began to run rough emitting some blackish smoke. I turned off the A/C unit and the gen continued to run rough for several minutes before clearing itself and running smoothly again.
Curious as to what was happening? And as clarification, only one unit was operating at the same time. Thanks.
