Onan 5.5 Marquis Gold HGJAB problem
For several months my generator start light on the starter switch stayed on all the time running or not. Last week it would start but die immediately when I released the switch, just like I had presse...

Thx for all the replies. My control board had issues and was not giving any codes. The light just stayed on all the time. The new board from Flight Systems gives fewer codes and seems to be more robust and only shuts down for low oil or no AC output. I emailed them and found that I was testing the single wire oil sensor wrong. The sensor wire has to be grounded to the frame to start and then ungrounded before releasing the start button. I’m busy a few days, but I’ll post back the results. I never saw that grounding process online or on YouTube.
