Onan 4000 generator cranks but won't start
Hi all, I have a 2015 Cummins Onan RV QG 4000 generator. It has somewhere between 300-1000hrs (not sure, I've only owned it for about 2 years and it was a previous rental...might not be the origin...

FYI....
For anyone in the Seattle area we have a great generator tech named Chuck. He's in Auburn, Wa. He agreed to come out to me (Renton-Highlands) and diagnose my Onan Microquiet 4K which would only run if I hold the start button.
I initially checked with a volt meter some pins and narrowed the issue down to either a bad control board or voltage regulator. When Chuck showed up he threw his Flight Systems G-Man 360 on it and within 5 min bingo...bad voltage regulator.
The voltage regulator that was on it had been replaced back in 7/11 with a Flight Systems 305. I was leaning at it being a bad control board.
So if you need a generator looked at call Chuck (253) 820-1388
