I recently had to get a rebuilt alternator for my tractor. I removed the old one, drew a diagram of where the wires went. Some how I lost the drawing and I am now lost as to where the wires go. It is a 3 wire alternator. The new one has different connection points .Any help will be appreciated very much.

p.s. there is a red, black and a grayish/green wire.

How did this turn out. Know it is an older thread but I have a 96 MF 231 with 2 wires from tractor and several onboard the old alternator but no wiring diagram with new one and only 2 posts. I posted a new thread before finding this one. Any guidance is greatly appreciated.
