Pre-alternator failure symptoms?

[patrick.bureau at gmail.com (Patrick Bureau)]

I agree, but often enought the culprid is not the alternator but simply the 
voltage regulator on the alternator where once your remove it (2 philips 
screws) will show the brushes are worn out and need replacing (12$/autozone)
 I would check them first... then again checking voltage output on the 
alternator (boost to start the car and test car) will give you indication if 
alternator/brushes are at fault or something else.
