Delco one wire alternator on a TO-35

Hey guys, got some more questions about my Z134 equipped To-35. When I bought the tractor, the original generator and regulator had been replaced by a junkyard Delco alternator which was not charging. I replaced it with a rebuilt "one wire" Delco alternator from O'Reilly's, which bolted up perfectly. The alternator is the type that will not start charging until you get the rpm's up a little. When this happens, the alternator will slowly increase the charge until it reads about 15 volts, which seems a little high. The original ammeter reads squarely in the middle while the tractor is in use, when you turn on the headlamps it jumps to between 5 and 10 amps on the positive side.
All was well for two months until this week. Now, when the alternator starts charging, it makes a loud squeal and sometimes even a minor grinding noise. I'm thinking the alternator has become damaged from being constantly full-fielded, or it is simply a defective unit.
I'm wondering if any of you guys have experience with the Delco one wire alternators. Do they still require the use of a voltage regulator? There is a threaded post on the back of the alternator near the charging post. Grounding this post reduces the output to battery voltage, maybe this is where a regulator is supposed to hook up.
If I opted to go with installing a factory generator setup, what parts would I need? I don't think the original voltage regulator is still on the tractor, or generator cutout. What does a generator cutout do anyway?
Thanks for any help you may be able to provide, have a great weekend everybody!!
