Had the stock 95A alternator in my 1995 Ranger blow up on me last week. Since then, I was able to return the exising unit (Duralast reman) and get a warranty refund (they honored the lifetime warranty, despite me buying it back in 11/2015. Yay AZ... too bad they don't seems to stock the right unit any more).
Today I went to Pull-A-Part and I pulled a 130A alternator out of a 1996 Explorer sport (looks to be a new-ish unit). I installed that unit on my ranger.
The alternator spins fine when the engine is off. However, when running, it's locking up/binding and slipping the belt badly. Lots of squeaking, and the pulley and belt were HOT after a minute of running. Not charging either. This wasn't the case before.
If this is an alternator issue, what would I need to replace (or would I be better off rebuilding it?). If not, what would cause that? The tensioner isn't fantastic, but it is pulling tension (ugh, as soon as I typed that I now think I have a culprit?). Nothing else is slipping as far as I can tell.
