Electrical Issue

[WCS755]

You need to trace the relevant wires back and unwrap the wiring bundle to see what you're looking at. It's a PITA but needs to be done

Thanks. I was afraid that was next. I traced the wires yesterday but didn't see anything obvious at the fuse panel or alternator. Most of the wires are bundled though. I will probably use electrical tape or zip ties to rebundle.

Before you tear into your wiring harness to far.
You say your tractor "stalls". I would be tempted to say your fuel solenoid is dropping out.
It could be a bad solenoid or the connections right at the solenoid. You have two coils in that solenoid a heavier pull in and lighter hold in.
It may be possible to mechanically move the solenoid lever to open your fuel flow.

Years ago I had a Farmall H do that while plowing. Ran fine to field, kept shutting off. After several attempts, a finally parked it. I found a broken diode in alternator. Quite annoying.

I'm really hoping it's something readily accessible. I have my eyes on the wiring plug at the alternator. The insulation is solid but the wires are bent at a 90 degree angle. All the vibration could damage them inside the insulation maybe. Did you disassemble the alternator?

No. Just swapped it for a rebuilt one. This was probably in 1981, cheaper to replace.

Could mice have chewed through the insulation on some wires ? Running through the wires from beginning to the end will usually reveal the issue in this kind of situations.

Thanks for the suggestion. I'm thinking now that the short is where the wiring harness passes over the engine block. It's a friction point.

Looks to me like joecdeere's got you COVERED!
NOW....how to get to him that CASE of his favorite beer!

I came to suggest operating the fuel solenoid manually if possible but LouNY had that covered. Good way to get you out of a bind short term, or save $600 or whatever Ma Deere wants for a fuel solenoid if that's the problem. Lots of other good suggestions too. Poking around the electrical connections with a temperature gun if you have one might help find a problem, particularly when it's cold out. Sometimes a problem is a bit warmer than the rest of the system.
