What causes our new belts to break after about 2 weeks?

(1992 Mercury Capri)
in Moneta, VA on August 25, 2010
When the alternator went bad, the belt had to be replaced.
About a week after the belt has been replaced, the car belt
squeels when starting and the battery guage drops to low
then goes back up to high. Then after about a week of
squeeling, the belts breaks. We have replaced the alternator twice and the belt 4 times. Our mechanic
cannot figure out what is wrong. 92,000 miles. First
time belt has been replaced was with the alternator

Sounds like you have a pully out of alignment. Puts belt at a angle. Or poss. (but not often) tensioner keeping belt to tight.
