Onan starts and dies, throws Code 3
We hit a heat wave and had to run our generator an Onan (HGJAB901A), it quit and threw a Code I believed was "Low Oil Pressure", I assumed it was due to low oil level and refilled. Now it just starts...

Fault 3 is a general code that indicates you need to check for a secondary code. After it does the 3 flashes, hit the off button only once and a secondary code will pop up. I'm having that issue right now with only 40 hours on the generator.
Your crankcase should only be filled halfway between "ADD" and "FULL".
Not sure if you are aware but you are responding to a post that's 7 years old. OP hasn't been on here in some time.
So maybe we should never respond to old posts?
Sure, knock yourself out. I wasn't trying to be critical. Some visitors have stated they can't see the age of the posts when they respond. It's a website problem we have asked to have addressed. I was just letting you know. And while your response may have been helpful to the OP, it's rather old and OP hasn't been on here in some time. Most of the traffic on here recently is from visitors responding to posts that are old, sometimes over a decade.
