Hello all, new here and could use a little help on my onan 12.5kw jc genny. Can’t figure out if I need a new stator. I wasn’t getting any ac so I excited the generator but only get 140 on one leg a 5v on the other. Don’t have a megger to check insulation values but I did do a resistance check and I get .3-4 on both legs. I do have good continuity and it doesn’t seem to be shorted to ground anywhere. Any help would be greatly appreciated. FYI I don’t know much about the machine as I got it from someone who had passed away. There wasn’t a transfer switch on it so I’m concerned he could have back fed it.
