Unhooking the pos cable does not prove anything, the computer is the voltage regulator and unhooking the battery just confuses the computer voltage recognition ability.

How can I test my alternator to see if it is discharging my battery?
You can have the alternator tested free of charge at just about any major auto parts store. By the way, a bad alternator will not "discharge" a battery - the alternator's function is to provide the charge to the battery. If the alternator is faulty, then it is not providing the charge necessary to keep other components from discharging the battery. I had the alternator tested and it was charging. If the alternator has a bad diode, it will discharge the battery. I replaced the alternator and everything is fine.

Drive home and then put a battery charger on the battery to fully charge it.
