The bearings and brushes are easy to fix, but if the slip rings have been 
moved on the shaft, that's a potential problem. The connection between the 
rotor wires and the slip rings is one of an alternator's weak spots. If you 
press the rings back into position, those wires have now been stressed 
twice. Check them carefully.

I agree. This is really disappointing.
