So My sons and I bought a 1986 Jayco 25ft Class C Motor Home. Of course it is not without issues most of which we can fix replace or discard. One big issue we're having is the on-board generator. It runs but does not put out any electric. We have gone through all the recommended tests to try to narrow down the faulty part but the parts are too expensive. My question is where do you find a replacement generator or do you just get a portable generator and use it outside of the motor home. has any one ever replaced one?
