you may have to reset it to get the correct fault codes: This is from Onan,
Now, if you've been gone and when you get back and the generator has stopped running, the Start/Stop Button will not be blinking. It quits blinking after 5 min. To get the Fault Code, Press Stop 3 times within 5 seconds and the blinking will start. You just need to count the First and Second Level Blinks. Example, blink, blink, blink - pause - blink, blink, blink, blink, blink, blink - pause - and it repeats. If you hit stop again, the blinking will Stop.
Once you get the correct number of blinks, you can start to trouble shoot
