There should be a circuit breaker on the generator, probably located on top near the "local" start switch. Check to see if that's been tripped. Bad batteries might have created a situation that tripped it. If so, the genset will run but won't provide AC power to the coach. Try turning the breaker off and back on.

I have found only one circuit breaker on this Onan and I have reset it. This generator won't start if this one trips so their may well be another one that I didn't see. I'll check and see if by chance there is a second one or perhaps an inline fuse of some sort. Sure appreciate your come back and hopefully a simple solution is the one that solves this problem. I can use all the help I can get when it comes to this little deal, I have found over a lot of years that I never seem to know enough when these problems occur. Again I thank you for the come back.

I forgot about that breaker. Not exactly easy to see on the 4k model. But, if you've checked that and it's reset, you've narrowed it down a little. It still is possible to have a bad breaker though. Unlikely but possible. I'm not where I can look at mine, but you could narrow it down by checking the AC voltage coming out of the generator with breaker on, genset running. If none, then it's possible for the breaker to be bad or maybe something else. If 120V +/-, then it's probably in the transfer box. If you're not comfortable doing that and know a fair electrician, they could help you out. Could check it near the genset or at the transfer box input. As for the transfer box, on mine it's located under the bed, which is next to the back of the main breaker panel. Very easy to following the wiring and see the shore power input, generator input and output to the panel. Most motorhome dealers stock one. A 30 amp model is usually less than $100. I'm not sure of the brand that FR uses, but there are several brands out there. Hopefully yours turns out to be a simple problem. There's only so many things that can go wrong with them.

At least in Heaven, RVs will be perfect, and I won't have to keep fixing them.

If possible I sure would appreciate any further help you could provide. Thanks again, John
Have you had this RV for awhile? I assume your positive you had power from the generator before you replaced the batteries? Just trying to gather some info, i know this thread is about an auto transfer but I don't see where you stated if yours was. Does it switch automatically or do you have to plug your shore power cord into a outlet on the camper to get power from your genny?

Forgot about that one Motocross. Think I overthought that reply above without enough info. Very seldom I see them without the auto switch, but I did see a new Mirada like that last year. In that case there would be no switch. Just the recepticle in a bay.

When I run the generator it powers up the electrical through out the coach automatically. The generator was working fine until I had to replace the batteries and then nothing except for the fact that I still have shore power throughout the coach. I also have power to the fuses and circuit breakers inside the coach with the generator but it doesn't go any further than that, seems that it simple dies when it reaches the fuse/circuit breaker box. It may well be that transfer box everyone is talking about. Since I don't know what it looks like I am kind of at a loss to check it, like one of the posts I have a lot of stuff under the bed in my coach including some of the electrical, the box may be there. I'll have to check to see if there is anything there. I sure appreciate all the information that I am receiving from many members, many thanks to all of you.

I'm a little confused. I'm assuming your unplugged from shore power when checking? If plugged in, I'd get off of the shore power and check the panel with the generator running. Both power sources go through the transfer box first before going into the breaker panel. If you do in fact have a transfer box, you'll find it. Should be a 10/2 w/ground romex (usually orange) coming from the back of the breaker panel for 30 amp supply. Not sure what they used on yours, but either way it should be the largest of wires going to that panel. That should lead to the box. Your shore power cord will also lead to it. I'll be coming home from offshore today and maybe I can take a picture of my set up and what the box looks like.

flyboy90, not sure if you have resolved your problem yet, but I attached a few pictures of what our set up looks like.

Thanks for the pictures. I haven't been able to solve it as yet but that will sure help. That will be under my bed as that's where my converter is. It is in one of those hard to get at area's as it probably is behind my water filter but at least I have a good idea of what to look for. I sure do appreciate all that have responded to my problem. I have been at the hospital for tests the last couple of days and if I have missed responding to some threads I apologize as I do appreciate any and all the help I have received. Again Thanks to all.
