[V8] Charging System?

[Dave Saad]

I would guess the brushes are worn out - which means a new voltage  
regulator unless you can figure out how to replace just the brushes.   
(not all that hard) If you can, the cost is about $1.00.  If I were me  
though (and I am) I would take the alternator out of the car and  
replace the bearings and generally clean up the whole thing.   
Basically a rebuild of the alternator. Doing this gives you a whole  
lot more miles of driving pleasure.  If the brushed are indeed worn  
out, that means the bearings have seen some miles to.  I seem to  
recall all the parts for mine came to about $80 (the front bearing was  
expensive) and I did the labor so $0 there.
