I'm sure you changed the belt with the alternator if not you should, however your problem boils down to the belt tensioner. Here is a good way to check, turn on headlights and all accessories with the switch on engine off to imitate a low battery then start engine and rev it a few times the turn engine off carefully feel the alternator pulley if the alternator pulley is hot or the belt squealed either thebelt or tensioner is bad hope this helps carefull of that pullet when I say hot well you'll see
