Another update, and I've about had it with this thing. Installed the two sensors, the one behind the air compressor and the one around the bottom. Truck ran. Went bobtailing around for a 1/2 hour or so the other day again, everything fine.
Hooked up to the lowboy trailer yesterday morning- we left the shop at 5:30 to go to a jobsite, load up the rt and be on another job at 10:30. I left a little cushion, because I didn't trust it yet, and its a good thing I did. It ran fine to the jobsite with the trailer on, we loaded up the crane and its about 1 1/2 miles up out of the jobsite, and the last mile is a steep 2 lane on a busy highway. At about the top of the hill, it coughed, and my heart stopped a little.
My prayer life improved a lot in the next 3 miles of narrow busy 2 lane (no shoulders), until there was a intersection I knew I could get off the road at. It made it there with a few more coughs and sputters, but it had me worried.
It did not display any code.
Off loaded the crane, called my buddy with his lowboy to continue the haul (was only 2 hours late for my job). Called the wrecker and hauled it to the dealer a hour away. I gave up. They called this afternoon and said they found the problem- harness from trs to ecm.
I don't know if they're right, but if they are, I'll dance a little jig; if they aren't, my mechanic and I are having bonfire discussions.
I will admit that when I brought the international over to rescue the trailer, I thought about loading the crane up and giving it a go with it. It's only a m11, and a super 10, but there's one bad hill in there. I've had it with a little over 80,000, and that was all it wanted, so I don't think 105,000 would be a good idea, but I did think about it. If there wasn't that one real bad hill, just flat ground, I would have given it a go.
