wiring diagram for MF270

Can anyone post the wiring diagram for an MF270? I've got a wire coming off the ignition switch that is going to ground. I'm trying to chase down what is pulling it to ground through the wiring harness. A drawing would be very helpful.

Thanks.
 
Tough couple weeks. I struggled with some brake issues and finally got that figured out and now I've got electrical issues. Not easy here with the snow when the tractor's on the blink.

I've been chasing intermittent grounds on my instrument panel and elsewhere.

I took the starter off (with solenoid) and bench tested it. It tested fine. On the solenoid, there are three terminals. There are two power terminals, one for the battery connection, and one that is connected to the starter winding through a copper bar. These I have back as they were. I can't remember what post the connections to the alternator go. The third terminal is the coil of the solenoid which is connected to the ignition switch (through the transmission safety)

I did think that the alternator connected right on top of the battery positive at the solenoid. I connected them like this but i got some sparking on the battery when I went to re-connect.

In order to get a wiring diagram, it looks like I need to buy the $200 service manual. I am going to buy this because I still need to find my original problem. The manual is going to take a week to get here.

Anyone got any thoughts in the mean time?
