Generator issue
The 12.5 in my 06 TSS shut off last trip, code 36. When I got home I replaced the fuel pump, fuel filter, changed oil and filter. This past weekend it ran fine first day or two then would get an occasional shudder but then smooth out. The shudder got more regular about every 20-30 minutes. BUT it kept 2 ACs running for 2 more days. Then on the way home it shuttered and quit, code 36. I cranked it several more times and it would a minute then quit. Next day I put new fuel filter again and it cranked and ran 2 hours. I blew the fuel out of the filter and it looked clean. I cut it open and didn稚 find anything.
What are my next steps?
Thanks!
Jimmy

My 12.5 in an 06 Select had all those symptoms of fuel starvation...even getting progressively worse over six months until it would only crank, but not fire.
Heard of another owner who had those symptoms, but he found the problem was caused by a poorly seated main electrical plug on top of the genny.
Reseated minr and it fired on first crank. Has run fine for a year now.
Plug difficult to see or get to. Gotta remove as much of the top cover near the front as you can. Work by feel.

Thanks. I’ll pull the top off Monday. I appreciate any and all ideas

I'd also take a really good look at all the fuel lines, your symptoms MAY be be caused by occasionally sucking air into fuel supply . ..

I知 out of town until tomorrow but I plan to dive back on it Monday. I知 going to check that plug but it still sounds to me like starving for fuel. I may replace the fuel lines as well. They are 14 years old

This is exactly what I went through. I chased fuel filter, fuel lines, fuel pump, and every other issue because it was always a Code 36 and sounded like the engine was being starved of fuel. I noticed the problem always came up when I hit a harsh bump, and sometimes it was out of the blue.
Over the past 2 years it's happened a few times, but not in a long time. I've got it down to the point I can take a 10mm socket, pull the degas bottle out enough to get my hand up to the plug - pull it out, spray it with electric contact cleaner, and pop it back in - about 10 minutes in a rest stop. I've just come to deal with it given how rarely it now happens.

Do I need to take the top off or can I get to it behind the water jug?

Can't hurt to try reaching.
The top cover immediately over the plug doesn't come off. I took off the first panel on top that is removeable, which is its own pain...because it fits under panels on both sides (I wedged it out).
It was still a reach into the darkness for the plug.
This plug is a marvel. For being so crucial to the operation, you'd think they'd give direct access, AND you'd think they'd have a more secure attachment!

Update. Genny ran for 30 hours straight with all 3 ACs on. Went to park it in the shed and it cut off. Tried to prime it to see if pump was working and it was not. 20 minutes later it cranked and ran fine again. The next time it quit I took it all apart and cleaned all the connectors and added dielectric grease. Still no crank. Checked voltage at pump while trying to prime and had zero. Ran a 12v jumper wire to pump and it started pumping and ran fine again. I GUESS I知 down to either the fuel pump relay or the board??

I replaced my fuel pump and it's a major pain. But I'm starting to wonder if you have a bad controller board. If you were able to bypass with a 12V feed and make it pump, that's sounding like something else (the controller) isn't telling the pump to keep it primed up.

I agree. The pump is obviously ok. It痴 either the board or the fuel pump relay. Monday I知 starting at the relay. I doubt if it痴 the board that I知 going to spend that much money. I値l add a three way switch and move on
