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

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 was DEAD before the disconnect.....
It was stated that the connection at the battery came loose. Once tighten all was well from what I remember.

I thought the car should have kept running too.
