Ijust upgraded my 65 Amp alternator to a 100 Amp with external regulator. It was really easy to do and I didn't have to rewire anything. It cost about $100.00 from standard battery company. I was told that this upgrade was better than the one wire set ups.

I have given some thought to doing what you did. I have an alternator from an '90 Escort and it sounds like mine and yours are the same. From what I figured out one wire is for an idiot light, one is for the alternator to "sense" voltage, and the last one is for output. The one I have is a sixty amp with worn brushes. It had a serpentine type six groove pulley that just happens to be the same length as the stock FE double groove pulley so I swapped them along with their respective fans. I haven't installed it yet because I need to know how to test the regulator, replacement reg's are $42.

Well, I don't know about yours
I don't know how to test a regulator
But mine is internal, and the fan is internal also
Best of luck, Im not sure what you want me to say. lol
But if you need any help feel free to ask
The way i tested mine...
I did it on the car before I took it off
I used a voltage meter and made myself a diagram

> They make crimpers for that yanno
I know, but, I was not at West Marine and had to buy the cable from NAPA instead and they did not have crimpers at this store. I do not do enough cable to justify buying a $50+ set of crimpers.

Taurus alternator: venting and pulley questions
Guys,
On this Taurus alternator, I have two questions:
1. What direction does the cooling air move through this alternator? Is it from the front (cool) to back (hot), or is stupid, like the stocker, where it goes from the hot back area to the front? Someone mentioned an internal fan, so it could be either...
2. Can the surpentine pulley be removed, and the old double-V fanbelt pulley be installed instead?

I forget which way it cools but its internal
Also, I used a 91 ford Tempo alternator, not a taurus, not sure if they are the same, but prob so.
On the car i got the alternator from, it was a vbelt pulley already. so no problem there.
