65 dart not charging with new alternator

So I’m going to take the advice on here and replace with the newer model alternator that I seemed to have instead of the one that supposedly fits my 65 originally that I basically made a mistake in buying. I’ll let you guys know how it goes thanks
Rather than throwing more money, post photos so we all can help you understand what is really going on.

All advice you have been given here is pure speculation since you have not provided photos.

I don't understand your reluctance to post photos.
