First off, I have proof of global warming. I took the tire chains off the tractors and unhooked the snow blower today, earliest ever.
This is tractor repair season, two piles of tractor are in the shop right now. I had got the 3600 running temporary, found it had a few more leaks to repair so I took it outside for a pressure washer bath. On the restart attempt, when it was soaking wet, I saw smoke come out of the start solenoid. Letting the smoke out is NEVER a good sign. Now it wouldn't start anymore.
Replaced the solenoid, no joy. OK this solenoid has TWO wires on the control side. I tested one wire and it goes from 0 to +12 if the key is turned and the neutral switch is set. Looks great. But I got +6 volt on the other wire. WTF??? I have no idea what the purpose of this wire is or where it goes.
I made up a white wire from the second solenoid control post and ran it to ground. Tractor now starts and runs fine, neutral switch works.
I'd have to pull all the body metal and cut apart the harness to find where this other wire goes and what its for. That's not happening. Any ideas on purpose of the mystery wire?
