All this Onan genny talk reminded me I had a new fuel filter to install. As I snapped it in, I looked around and can't believe the thing runs at all. (but it's running sweetly)
You can see here two positive wires coming into this thing but no ground. What is that, the fuel pump? I guess it grounds itself.

And look at that wire with no place to go on the left side. It's a female blade connection and I'll be damned if I know where it's supposed to go.

There's a few fuel drips outta' this thing and it needs a lot of time. But it'll keep running until I spend a bunch of money on it. That's the way it works - they don't die until you pay for an overhaul or spend days working on it!

Re: Onan Generator stalls after oil/filter change
Glad you got it.
Every 100 hours??
Both fuel filters?
How did the Racor bowl look? Do you drain them when servicing?

Re: Onan Generator stalls after oil/filter change
Yeah, those red crimps are probably the only new material on the thing.
I wondered if the loose wire I have on the left was the one you were talking about. Seems it would have gone under that wall to the left and up into the control panel area.
I hope I didn't yank it out of somewhere when I was tinkering with the bad connections in that voltage regulator area.At the mouth of the Caloosahatchee

Re: Onan Generator stalls after oil/filter change
If your oil changes are very 100 hours you can do the fuel filters every other change.
The two wires with the red crimp are connections to the fuel shutdown inside the injection pump. If you look right across there is a terminal with a metal strip. That s the ground
Not sure about that loose wire, could be the connection to a gauge sender? Is there a sender above it on the coolant tank?Pascal

Re: Onan Generator stalls after oil/filter change
The wire on the left goes to a temperature sensor mounted on the exhaust riser. It should ground and shut the engine down if there is no water flow out the exhaust.
