Also, the cutout relay has three terminals, but the wiring diagram I found for a Farmall tractor with a cutout relay only shows two wires connected to it. Should there be anything connected to the third terminal?

It has been a while since I've done this -- as I recall the threaded 
portion of the fan pulley needs to be turned to _increase _the belt 
space width.  Then slip the new belt around the fan blades one at a time 
trying not to bend radiator fins!  When the belt is installed over the 
fan and generator pulleys, adjust the belt tension by tightening the fan 
pulley (decreasing width of spacing).  Suggest rechecking the tension 
after a few hours of running.

The first pulley I worked on was virtually frozen in position over the 
years -- so it may take some patience!

I installed a single wire GM alternator on my MD so don't recall about 
cutout!
