If the engine is RUNNING and the alternator is not alting (Joke, Not charging) then the alternator is bad. Remove and take to a rebuilder.
IF the alternator draws power when the engine is OFF (Yes it can do that and not be bad) I had that happen on one car. Turns out the alternator case was not properly grounded to the engine block. NOW I know this is .... Rare... I mean the thing is tightly bolted to the engine block, but that was the problem.
I put a "Star" type lock washer on the bolt and all good.
