Here is an old mechanics trick. Find a long stick (or screw driver) and
place one end on the end of the generator near the bearing. Put the
other end up against your ear. You will be able to hear the bearing. If
it sounds like a grating or grinding noise, it's toast. If it sounds
smooth, your problem is elsewhere. The hard part is listening to the end
where the pulley is. Be VERY CAREFUL working around the moving pulley
and belt. If not, it might be the last work you do on your car!
