Here's the bad part of that whole thing: The alternator is charging... nothing.

It's building a charge, which it then has to shed somehow. Probably as heat. That will probably eventually kill your alternator.

Gm's 1 wire alternator isnt' really an alternator, IIRC. I'm pretty certain it's a permanent magnet generator, which later routes power through a voltage regulator. That being the case, it's always charging something, which is why lots of those older cars always have some electrical load running, so they don't overcharge the battery.

My $0.02, FWIW.
