THis "test" was a short cut way back in the 60's left over from post war vehicles with generators.

Loose power connections have shorted out more electrical components than anything else in history. (An assumption on my part. No actual data collected...)

Regarding a vehicle that dies when the battery is disconnected: A good electrical system SHOULD have kept it running. But who knows what failed at the same time as the disconnect? The Regulator? The main module? The ground wire? Who knows? Maybe the alternator/wiring was DEAD/shorted before the disconnect.....
What we are failing to take into consideration is not just the voltage but the amps draw when Terminator lost power to his X. He was running at night with all the lights on and if it was in the dead of winter he might have had the blower motor on for the heater and imaybe the rear window defroster.

I have driven a car with a bad alternator on a battery as long as any non essential electrical device were left off including the radio. When the alternator to my PORSCHE crap out on me, I brought a new battery but only drove during the daylight hours. I was able to make the 40 miles trip back home on just the battery.
