Alt lock up

Beat the Heat

I put on a different alt and new belt, no squealing. Im not sure Ive solved the problem permanently though. The old alt. seemed to turn as smoothly as all the others I have around here. This is the second belt in 10,000 miles too. Im not sure whats up. The pulley on the old alt. may be worn or the alt bracket may be bent and out of align. It looks alright to the naked eye though, Im stumped. Ill give this set a chance and see what happens. Video below

You need a straight edge across the pulleys. There should be no visible gap at every edge.
