Title: generator shutting down
Post by: Charger1204 on October 05, 2017, 02:00:15 PM
 I know that this has been asked before but nothing really fit my problem so I'm asking again...
  I can turn on my 4k onan generator on my Winnebago Vista 26 and then turn on my A/C...runs fine, in fact it ran for over an hour the other day. When I started the coach to drive down the road, the generator shut down before I could get 5 miles down the road >:( It will start back up just fine and run...as long as I'm not driving with the A/C on, Any thoughts?
 Thanks,  Brad

Have you checked the oil level of the generator? It may be on the hairy edge of shutting down because of low oil level and when you start down the road, the oil moving around the sensor tells it to shut down.
I just read yourgain post and I'm getting the impression that the generator will run OK all the time as long as the Air is not on. Is that correct?

Rene T...That's correct, the generator will run while driving down the road as long as I don't turn the house A/C on. And the oil is the very first thing I checked. Very odd. I've checked the fuel line as much as I can see and it appears to be good. I would have to drop the tank to see all of it completely to the tank.

Oh, I was assuming this was dash air you were talking about but it's your roof air. How does the generator shut down - via a signal to the stop switch or is the breaker tripping?

The gen just bogs down, like it would if you tried to turn the A/C on right after you start the genny. I've tried to catch it shutting down so I could see if it gave a code while bogging down but I've not been able to catch it. I've put some seafoam in the tank to help get rid of any carbon or gunk build-up. When I purchased the MH it was 5 years old and only had 34 hours on the generator.

The 34 hours kind of gives it away. The carburetor probably needs cleaning or a rebuild/replacement. These carbs get clogged real easy while using today's gasolines and when not used regularly.

I think Stu is on-target with his evaluation.
