New alternator, not charging

About a year ago the original alternator finally had the bearings let go, so I got a remanufactured one from advance Auto parts. It was working just fine, no problems with charging until the week before New Year's it's fried itself in spectacular fashion spitting pieces of copper all over my engine bay. Got the warranty replacement for it, and now I'm not getting any charge at all.

I am very much not good with electronics so I'm not sure where to look next, but I am wondering if the alternator going boom might have hurt anything else in line?
Can you give us year make and model? Engine? If it's an early one, you were likely given a dual field alternator and one of the field spades needs to be grounded. More info would be helpful here.
