i think we just talked about this a week or so ago. i beleive mike(j9fd3s) said that if the car runs without the battery, the alternator is fine. if it fails, then the alt is not working properly.

get a battery/alternator tester is the easiest way to find whats wrong

Yep, thats right, The battery is only for starting it, then everything electrical runs off the alternator. If your alternator is bad, your battery will go flat because its not being recharged.
