Heh, heh. That's the "old school" domestic-iron method of determining whether you have a working alternator. Before DME's/ECU's/PCM's/EIEIO's, you could disconnect your battery, and if the car died, it meant your alternator was out of commission. Of course, if you try this with a modern car, you're just asking for an expensive repair.

(I still hear about LT1/LS1 Camaro guys trying this from time to time. They invariably destroy the voltage regulator in the car, which is integrated with the alternator in those engines, meaning that they end up having to get a new alternator because of their attempt to determine whether they had a bad alternator. Oh, the irony...)
