The heaviest load on the generator occurs right after startup, because that's 
when the battery has just been discharged from the starting cycle. If the belt 
is squealing, however, that is a sign that it is just a bit too loose.

Remove the generator, move ONE shim from inside to outside on the pulley, and 
reinstall the generator.

It is likely that your brushes are worn out. They should be replaced if they 
have worn to the point where they no longer stick out above the holders they 
slide in. It's also possible that they were just sticking, or that the pigtails 
were restricting their movement so that they couldn't move in any further as 
they wore down. They need to be free to move. The pigtail slips down in a bit 
of a notch in the side of the holder, but once it reaches the bottom of that 
slot, the brush is shot.
