Hi Gene,


>From the symptoms you describe, it looks that probably 
it is just the carbon brushes that are shot.
These are in the $5 - 10 range.

I strongly recommend that you examine the alternator first, 
as I have found that several "rebuilt" alternators are c**p. 
IIRC you need a 1/4" AF hex socket for dismantling the black cover at the rear of the alternator.

Just my $ .02 worth.
