It really is not that unusual for an alternator to drain a battery. I seen it several times. Its normally a drop of soldier that the culprit, however, the amps and volts are putting out what they need to to read good. disconnect the alt for the given amount of time that it takes to drain the battery, or go exchange it for another one if they'll let you. They probably wont want to, but be nice to them and they might. Most people would not want the hot battery wire dangling in a hot car, I wouldn't, but then I would change it with another alt I have laying around wheather it was any good or not. I just want to see if the new alt is pulling a draw or not. Some draws are so small that it takes time pull a battery down and then some will go quickly. If you cannot use conventional methods to detect the draw, go the hillbilly way. Replace it and see.

Or, if you have a volt meter, check the voltage across the battery posts while running. If anywhere around 14 volts shows, you're alt is charging.

Thats battery voltage only. Your alt is cooked, toast, veggie juice, finished, kaput. If its new or still under warranty, you'll need to take it back and exchange it.

Easy way to see if the Alternator is charging a usefull current, is to unbolt and remove the positive lead on the battery with the engine running. If the motor dies out, the alt. is shot.
