You could have your alternator output checked if you think its putting too much out these alternators have a internal regulator could be regulator bad. You can't buy parts to rebuild the alternator they won;t sell them. If you know some one who rebuilds alternators who has good supplier you might get lucky and he can get the parts.A rebuilt one runs $180.00. And your gonna need a repair manual if you put it in yourself they a ***** to put in or take out. You have to drop the subframe 3" and be careful of your bumper fascia when the frame drops down if it catches it will break it.
