I agree that it sounds like the prior owner converted it to an internal regulator alternator.
What may be adding confusion for you is a trick in the wording. When you go back to the wiring the prior owner had done, you are not getting rid of the voltage regulator! You are just using the one that is housed in the newer alternator. You just don't need to use the original external regulator.
If in doubt, pull out the alternator and take it to a good autoparts store (if there really are any out there) and ask them what type alternator it is. At the same time, it would be a good idea to ask what cars it originally came out of, in case you have to order another at a latter date (keep the information in a small note book in the glove box)
As for those wire connections; make sure that they are soldered together! A flaky connection will cause hair loss while trying to find the problem (I'm pretty much bald).
