I started the generator and turned on the roof air and it did not work. The microwave time came on but when I tried to turn it on the time would count down but would not spin. I checked all the fuses and the converter box had a fuse fried. I changed it and still did not work. All wires and fuses look good. I plugged into shore power and everything worked perfect. Generator starting up no problem. I'm confused. Can someone help me on this. Can someone help.

Does the light on the MW go off after trying to use? Do CB pop after trying to use the AC?

Electrical problems - not fun.

Since the AC comes on when you're on shore power, that tells you it's not a breaker in that's going to be in the regular circuit breaker box.

Since you're not getting power when on the genset, you'll have to trace it up between there and the transfer switch. Many generators have two A/C outputs. If yours is one of those, you will likely see two circuit breakers on the generator set itself. You can trip one, and not the other. Try flipping both to the OFF position, and then flip them back on. I have had one tripped and it didn't "look" tripped.

If it still doesn't come back on, you may have an issue with the power management panel (if you have one). We had a 2005 Fleetwood Excursion, and it would do load shedding when on less than 50 amp power. You potentially could have issues there.

If you're not where you have access to a mechanic (or just not ready to go there, here's a last desparate measure. Turn everything off, hit the chassis and house battery disconnects, and then go DISCONNECT the negative terminal on both sets of batteries so everything is truly dead. Give it a minute or so, and then reconnect it. If you've got a flaky relay in there somewhere, or possibly some energized switch that may not have reset correctly, this *may* get you back on the right track.

While it shouldn't matter, you could check and make sure the breakers aren't tripped on your inverter either. Wouldn't think this would be involved, but we had some massive electrical problems last year that ended up being an issue with the inverter being turned on manually in the bay instead of being controlled by the switch in the coach as well as a few other contributing factors.

Let us know what works for you when you figure it out.

fuses in the'converter box' are 12v circuits, lights, water pump, fridge controls etc.

MW and A/C are 120v only

either the circuit breakers located ON the generator are tripped
or the automatic transfer switch/RELAY is stuck/bad

do any of your 'outlets' work when the generator is running and shore power is UNplugged


Options, always have options, and the journey goes much smoother

You must first establish if the generator is putting out any voltage, so try something in the 120vac outlets to be sure. If not then it's possible the the gen set itself isn't putting out for whatever reason. If you have a plug-in receptacle for that, then it should be easy to check. If not and you have a transfer switch then you should be able to check there. Either that or remove what panels are necessary on the genset to check for voltage at it's circuit breakers. Some of your appliances require 12vdc control voltage to operate, so this further checking is necessary for finding the root of the problem.

Thank you all for the feedback. I'm gonna fine comb everything you all said again. I did everything you all said. Now, I contacted an old friend and he said what was the genny putting out and I said 60. So he said maybe one of the spark plugs went bad! I replaced one and didn't no that there was another. So I will try that and let everyone no. I'm so glad that we can all try to find out these things so when it happens to one of us (like me) we can go rite too the problem. Thank you all.
