Generator stops while driving
We are on the road with the generator on....air conditioning has been working for about an hour...then shut off. We have tried to turn it back on several times...no luck. Is it overheating?
Any suggestions?

Is the oil level full, if not it will shut down. Sounds like a heat problem, not getting enough air to cool. What MH do you have and size of genny. Others may have some advice for you.

Genny is 4,000 not sure of MH. We will have to check the oil once we stop....good idea. Now I have to find my generator manual. Thank u

Just a thought.....don't overload the genny, such as micro and a/c same time, or water heater etc.

Depending on which coach you have, you may be having an overheating problem. Several owners with 4,000 generators have had to make mods to allow for better cooling, again depends on your coach.

Expanding on SuperD's comments: Where on your coach is the generator? Is it in the rear? Is it in the front right next to or near the engine?
It is difficult to advise when you haven't mentioned which motorhome you have? (Miramar? Hurricane?) and which model?

By "modis": what sort would you suggest, to allow more airflow to the generator?
Would adding some underbody ducting; to funnel more air up to it help?

Common Thor Engineering Design problem. Documented multiple times for coaches where the generator is installed directly behind one of the front wheels. The generator operates in an environment hotter than it was designed for while traveling. A search will give you more information than you want on this or IRV2 forum.

What is your main fuel tank level at? Mine has a feature that if the fuel level gets down to a low point, the generator will shut down. This way you can not strand yourself without fuel.

Thanks!
Some of us newbies haven't had the unpleasant experience, or been in here long enough, to know what has or hasn't been discussed...
What is this "IRV2" thing that I keep seeing references to?

Thanks!
I think that I'll just swim around in here, and see what I can learn...

This one caught us on our big trip. The manual said it would cut off around 1/3 tank of fuel. It actually cuts off when the gauge reads just below 1/2. I panicked the first time it happened, now I just watch the gauge closer.

I've posted details and photos here in other threads
but to summarize what I did...and seems to have been successful in my case
1) I cut a hole in the door to line up with the generator's fresh air intake. Covered it nicely with a louver i bought at west marine
2) I fabricated a baffle using aluminum angle and some rubber sheet so that the generator has to pull air through the vent and can't get it form behind the door
3) I insulated the fuel hose form the generator all the way back to the tank, using regular plumbers pipe insulation. I used the nicer EPDM rubber type, not the cheaper foam, and I coated it with spray on autobody undercoating hoping it'll last a bit longer. While I was at it, I re-routed the fuel hose out of the hot slipstream of air under the coach, and tucked it much more nicely up against the frame
other ideas I've seen tossed about, and I was considering them in my back pocket if my changes didn't work...in no particular order
add a second auxiliary low pressure fuel pump back closer to the tank to "push" fuel to the genny's pump
add a return fuel hose form the carburator back to the tank so that the fuel pump(s) flow more volume than the generator needs all the time

Mine does the same thing, sometimes it will run for hours and others it stops after a few minutes and then shuts down. Only happens while underway. It will run forever if we are stationary. I mentioned it to the dealer and it is covered under the extended warranty but I have to be able to prove the failure and I haven't figured out what the cause is so I can recreate the failure.

Mine has done about the same thing for over a year. I ran a ton of Sea Foam through it and now it will operate in higher temps.

Did you run the Sea Foam from the main tank?
