Roby, is the alternator plug on the rear face of the alternator with the plug terminals mounted like this {ll} ? If so it may be a Delco 10DN that needs an external regulator.
If the plug is on the side of the rear edge of the alternator case with the terminals mounted like this [--], then it may be a Delco SI series with built in regulator.
I am not familiar with a 601, does it have an amp guage or a charge light ?
If it has an ammeter, the big BAT stud on the alternator rear should connect to the ammeter post opposite the one that goes to the starter/ battery. If no ammeter, connect the BAT stud wire to the battery at the starter switch. The Red #2 alternator lead is also attached to the BAT stud on the alternator rear. The white #1 wire connects to the gen light if the tractor has one, if not it goes to switched ignition power with either an added gen light or a diode inline in the #1 wire, somwhere between the alternator and ignition switch.
If you do have the 10DN made for an external regulator( plug terninals like this [II]), let me know and I will post a wiring digram for that external regulator type alternator.
