Looking at your picture both studs/posts are isolated from case ground by the white insulator . This indicates to me that these are positive . The one on left in the picture has the short red cable going to ground . I think this is wrong .
You might ask the alternator shop how they wired it on the bench , as per Richard .
It is possible you have a drive issue , but I would think it would have been evident when you removed alternator. It drives off the blower shaft .
When I was going through Leece Neville I found information on the Prestolite site , spoke with a knowledgeable tech .
I am looking for pictures of my original alternator, it was likely the same as yours.

BTW , that is your external regulator with 14v and a part number on it .
