You will be better off using a 3-wire Delco (10SI series) alternator. Will cost less, charge better at startup and is less likely to run down the battery if the tractor is not started for long periods. Also will properly operate your idiot light (a 1-wire alternator will not).

Wire up the 10SI as follows:
- Large wire to the alternator BAT (output) post
- Relocate wire from the #4 terminal on the old VR to the #1 aux terminal on the new alternator.
- Connect a jumper from the new alt output post to the #2 aux terminal.
Cutoff/tape all other wiring at the (unused) VR plug.
This is what you currently have for wiring on your tractor.
The only problem you may encounter using Bob's solution is that if your light bulb fails the alternator will not start to charge. A resistor of equal or greater value than the light bulb connected between the #3 and #4 wires at the regulator will overcome this problem.
The #4 wire can be connected to the #1 or F terminal wire at the old regulator and then use that wire to connect to the #1 terminal on the alternator.

Out of the yard, over the cows and bale piles, through the dozer piles, poplars, and brush, out onto the ditch grade road, past the noisy 6.2 diesel engine pulling my well traveled Suburban along. Well it sure didn't take me long to figure out what it was because I alrea
