Another little update...
Turns out, alternator was wired correctly. I do have a few extra cables, and when I get it running correctly, I'll be snipping off the ends of those cables to prevent future confusion.
I removed the alternator and took it to get tested. It was
barely putting out 13 volts, so I ordered a rebuilt from Autozone. The total with core return: $244.90, with a lifetime replacement warranty. I guess they don't expect me to hold onto 'ol Noami
So, after work this afternoon I'll throw the new alternator in and see what happens.
