OK, update time.
I got a new (used) wiring harness...and it still don't work. At least now I don't have to check all around to make sure that reason I'm gettin 0 volts is because of some frayed or completely separated wire. Install went along fine, took a few hours, and while I was doing it I filed/sanded all the contacts on the harness itself and on the tractor.
Terry Busch posted a schematic a while back (on December 4). In my reply, I said, amoung a great number of other things, that I couldn't give results due to the destroyed harness. When I did get results I found that the S/G no longer worked and the Solenoid buzzes. Same thing now, except I got data all around (sorry bout color, e-mail me if you want a better copy).

The checklist provided indicated the key switch as a problem, so I checked that out. I jumpered the the B and S wires (black lables, IE the green and orange wires) together, got a spark, but still got 5.5 V. I also tried every thing out with the Safety Switch (Orange and Black & Orange wires) jumpered. I'm guessing its the solenoid, but I don't wanna jump up and blow cash without some outside input who isn't trying to sell me something.
The S/G still don't do a thing, even with the battery hooked straight to it. Lots available on eBay, but I rather fix the one I have (if I don't have to spend forever doing it).
Being a student it seems weird to say that I'm not happy about the snow coming to possibly cancel school, I won't be able to clear it. Lost joy<lost profits. Go figure.
Oh, and a thumbs down on Mrs. Green Pants.
