Poised

Digging into the, what seems to be excessive, draw of The Beast's electrical system.

It appears to have been a decision on the part of Holden or GM engineers that the body control module never quite goes to sleep.

It stays more awake than the Australian version of the car to make sure that essential police equipment gets a trickle of power and to decide how much.

This amounts to about 0.4 amps.  Which is a lot for a car that's shut off.

The "problem" area is the extra fuse box under the driver's kick-panel.  This is where the fuses for all the Americanizations live.

But, the GM engineers reason, cop cars are constantly in use, the extra draw just won't come up!

And knowing about the draw being normal means I need to start the damn thing at least once a week when the battery is connected or keep a charger on it.

PS: Don't feel too smug about your own car shutting further down than mine, OnStar is calling home every few hours and transmitting.  The dear, departed, Precious would drain the battery sitting idle too.
