This isn't entirely true, when the ecu grounds the alternator control circuit "C" wire, the alternator does drop to 12.5 volts, but it is in fact still charging. I tested this with an almost dead battery that couldn't start the car. I jumped it and while grounding this "C" wire the car ran just fine.
