Tony,
Your part may be BAD now!
I'm not clear from the information you have posted, but will mention a few thoughts/questions.
There are several alternators that look similar, but are different..one is used with external regulator, the kind on the firewall. The other kind, which is more modern, has a internal regulator.
In lieu of a part number, the 'two prongs' would be the giveaway.
If the 'prongs' resemble this..II..the alternator requires a external regulator.
If the 'prongs' look like this..- -..It is a SI style and has a internal regulator.
To start with, you need to figure out which one you have. The hook up similar, except one needs a compatible regulator.
Your wiring description above didn't mention a third wire...where did it go.
Find out which alternator you have and many folks will jump in and help. This is a constant subject of discussion here.
The common name for the 'prongs' is a DA plug.
