The engine of our generator runs but it is not sending electricity to the Motor Home. Any solutions? It appears all circuit breakers are proper. I can not find one on the generator.

I have a Onan 7.5KW Diesel generator and then same thing happened to me. On the top of the generator next to the start switch is a lever/button which is very easy to accidentally turn off. You might want to check that out. I have hit that switch a number of times and the generator motor runs but no electricity.

You didn't say what make you have. My Onan has breakers on the gen. You might check the transfer switch.

The generator won't run unless it is producing electricity. It shuts itself down if it doesn't see 120 vac being produced. All Onans have a breaker and many have two. One for a 30 amp winding and one for a 20 amp winding. When you find them make sure you turn them off and back on to reset them.

Had my onan doing the same. Hit all the breakers I could find, even changed out the automatic switch. Finally took it to an onan repair shop and turns out the brushes were dirty and not making contact. Cost me about $200 to do something I could have done had I known.

Thank all of you so much. Will attempt to find those on generator breakers and switch. Any hints as to where they may be?

If it were where I am I would have included it is stored 50 miles away. It is green and we have a 30 amp 2000 Pace Arrow 35'.

my guess is an Onan and the breakers should be just to the right of the start, stop switch.
good luck.
