alternator question

See the pic. My alternator has what I think is a regulator mounted on the top of it. See the red wire going to the post. There's also a plug from this that can go into the alternator. The wire from the wiring harness also has a plug on it, visible in the pic. I can't remember which plug was used when I pulled the alternator a while back. I do recall the red wires from both the harness and small mounted box went to the same post on the alternator.

Tried to attach a pic, hope it worked

Re: alternator question

It looks like a previous owner got creative with the wiring. I would trace those wires back and see where they go. Does the car have a voltage regulator mounted on the radiator support? If the terminals in the alternator are arranged like =, it is an externally regulated alternator. If they are like this _ _ then it is externally regulated. I suggest making sure that the braided stainless hose is kept far away from that stud where the red wire goes.
