I tell you what, I'm almost to that point with this gen trying to figure it out.
I Know I'm suppose to have the model # & all ready for you folks, so here it is,
1998 Emerald 5.5BGMFA26105H.
We use the gen to run the a/c going down the road in hot weather.
It is realy crazy what is happening, we can be riding down the road for miles, can even have both a/c units running & everything is fine, but the instant a real hard bump in the road is hit, the gen will shut down.
I've tried it with the one front a/c working, the fridge on LP gas & only other thing on is the 12v converter & soon as a big bump, off it goes.
Now the other week during our SD trip, it cut off three different times while we were stopped for a short breaks.
I'm only guessing, that was from the high outside temps around 98* & the gen compartment getting so hot.
At one stop, about 5~10 minutes it cut off, so I got the temp gun & temps inside around the gen area were in the 190~200 range. The one cylinder head you can see, the temp on it was 210*.
Just thinking, could the fuel pump be vapor locking or just getting so hot it will lock up & then when cool start back working again ?.
If that is whats happening, its kinda weard, because it will shut down instantly like as if the switch was cut off.
A normal small engine, if it has a fuel problem, will have a flutter like hesitation before it shuts down, kinda giving you a warning before hand, but not this gen.
This RV, has no vent in the gen compartment door to provide cooling air from the outside, just pulls air from the underside, & normally when we are parked & have to run the gen, I have that door open & never had a running problem.
I believe it could run long enough parked & the door open, to empty the 79 gallon gas tank & never miss a beat.
Another odd thing, I've not done it but like two times, trying to get the next gas station to fill up, has been under 1/4 tank both times & gen has never even acted like it was going to cut off.
Now I know this sounds odd, but the 89 GBM we had before this 99 H/R, had a 6500 Onan & it would cut off when hitting a big bump in the road just like this one, so could it just be something about Onan gens we got to deal with.
