[V8] Battery discharge issue...

[dsaad at icehouse.net]

If you are getting no less than 13.8v and no more than 14.7v at the battery
terminals then the alternator is probably OK. Under a full load, you may have to
go up to maybe 1500 RPM but that should be enough. Turn on everything electrical
you can find - hi-beams, rear defrost, seat heaters, etc

>From your description, the alternator is fine but the 1.5 amp drain will kill a
battery. remove the door switches for any doors you need to go in through (to
keep the interior lights off) and shut down the car. Besure to trigger the
retained power relay by opening the drivers door and watch to see that the red
lights go off in the window switches. If you still have a current draw then the
usual course of action is to start pulling fuses one at a time to see which one
causes the problem.
