Spent the night at a BIG Texas Rest Stop. Only load I had was the fan for the furnace. I had turned the 120V refrigerator off for the night. I am sure I didn't need the gen running but didn't want to be stuck without enough power to start the Gen to pull in the slides in the am.

So around 6am after about 8 hours run time it quit. I assumed it had ran out of propane.

Later in the day after getting fuel at Loves I decided to fill the tanks. HMMMMM first tank had around 3 gallons left and back tank was full.

Got to camp and sure enough the cooktop burner lit and so did the Gen.

Why would the gen quit with no load other than replacing the heater fan use ???

It was 13 degrees out.

Did you check the oil level?

The gen is 5 years old. It's a Cummins/Onan 6500 220V with only 88 hours.

Is it possible the regulator has something to do with this?

Can't say, as to oil issue on a built in, larger gen, but you likely know, the smaller portables need to be very near full, to avoid possible shut off.

Thanks Jerry!

Wish I would have checked things out further at the time but at 13 degrees, NO THANKS!!!

Guess I will change the oil as it has 45 hours and 2-3 years on it.

Pic of transfer/regulator. Should the window show "Green" when ample Propane is present and "Red" when empty?

13 degrees? Froze up the propane tanks. I know they aren't really frozen, but you know what I mean.

Mine do, would expect, from pic, that yours are similar.

Not sure at what temp, but at cold temp extreme, propane does not flow as well in 20-30 lb cylinders, especially if cylinder is less than half full. Some will use a 100 lb bottle type, for this reason.

I do not know about propane Generators but on "Main engine Fuel" generators the generator runs out of fuel "Early" (like 1/4 tank) First time My Genny quit on me I knew this but did not know I was at quarter tank till I turned ye old key.

Most LARGER propane generators suck liquid propane so when the liquid level drops BELOW the outlet pick up.. IT starves and dies.

I stress however that I am GUESSING.. Not an expert on that type.


Home is where I park it.
