NEW INFO
I put the SCT flasher unit on it and tested for trouble codes (even though the CEL is off) and it came up with a P1246 - Generator Load Input Failed (All Others) It was at this point I realized that the CEL should probably be on as well as the Battery light. They do however come on initially when I start the car, and the battery light comes on if I unplug the voltage regulator. I don't know what to make of this, but it seems like it probably has something to do with my problem.

Yeah, that was the first thing I checked when I realized the alternator didn't fix it. Without it I wouldn't be getting the power on the red wire. I would order the rebuild kit as you suggested but I really don't think it would help. I've replaced the alternator twice in the past week with new alternators from different companies and the symptoms have remained the same.

Thanks for the info. It left me a little confused though, I was under the impression that only the European cars had the "smart charge" feature, mine is US spec. Am I missing something?
