Onan Generator

They do NOT shut down due to "service due". When they have a fault and DO shut down, that Service due indicator is given. It is telling you, that odds are there is a part that has either failed or is intermittent and find out what caused the shut down. BUT, as I stated, the Gensets will NOT shut down if regular maintenance is due or required. Doug

I was parked on an angle one night and mine shut down. It thought I was low on oil. I leveled it up and did not have that problem again.

It probably was slightly low on oil and the angle caused the oil level to allow a small hiccup in the oil pressure which caused a Low Oil pressure shut down. Same thing happens when in transit and the oil is slightly low---you make a hard turn or stop and the Genset shuts down due to the oil in the crankcase shifting causing a momentary loss of oil pressure.

Oil and coolant were both good to go

does the control panel say "service due" or "service required?"
whenever this generator shuts off, and you did not push switch to
initiate shutdown, the light in switch will blink a code; 1-hi temp,
2-low oil press., 3-everything else . this is first level code, you have to push switch to "stop" and release it while it is displaying 3 blink code, and the contol will give 2nd level, 2 digit fault code, identifying which system on genset has the problem. your operators manual should have this procedure in it, and a list of fault codes and
a description of what they mean. The factory service manual is much more detailed in diagnosing and repairing the codes.

coolant?

Just in case it was an overheat

After seeing the car with radar run over the mother and baby carriage rather than hit the car, I'm not so sure. Anyway, mine just indicate service but it's a2007 7000.

The 8K and a lot of the other diesels are water cooled. Just learned that the other day. Also the 8K is variable throttle based on load, whereas the 10 and 12K are fixed throttle.
