New Onan generator
Purchased new Onan 4000 ultra quite generator. Had it installed last week. Worked great for 8 hrs. Now when load is put on generator it bogs down. Before any load the plugs voltage read 120v. Turn on just AC. AC comes on a few minutes then bogs down generator. Reading goes immediately down to 90v then either AC kicks off and generator builds back up or both goes off. Same outcome if I only run the microwave so it’s not a bad AC compressor.
