ok i need help BIG TIME! everytime i shut off my car something kills the battery..and fast try like 15min-to a 1hr at the most to completely kill the battery ! it just started this out of the blue!? just for no damn reason it started this crap!i had everything like the alt and starter tested!FINE!i tried disconnecting every single fuse one at a time and left it overnight and the batt still went dead !!!!!the batt is also new and have had it tested and load tedted many times its fine?! i have to disconnect the positive lead of the batt everry time i shut off the car!!!this is of course very annoying!!!!i have checked the fusioble li9nks aT THE batt alt and starter and still they are fine and it continuse to die?wtf? why? i put a new groud strap on it today and it slowed the drain from 15 min to a full hour maybe 2hrs if im lucky! i even disconected the horn altogether.i am at a point where i want to shoot my car ........HELP!!

What is the voltage with the car running at idle?

What is it with the engine at ~1500 or more RPM?

What is it after the battery has been charged (after having started the car), say after about 10 minutes?

I know you said the alternator/battery were tested, but maybe the output of the alternator is not getting to the battery properly for some reason. I am thinking this because you said that the battery (with the car off) would last longer another ground cable was added. That, to me would indicate that the alternator would be able to charge the battery better (due to a poor ground soemwhere?), and thus have more capacity, or have a longer discharge time.

But having a better ground with the engine off (alternator not charging) could only increase the current drain, or shorten the time before it goes bad, but you said adding another ground made the battery last longer. Having a poorer ground (with the engine off) would make the battery last longer due to the increased resistance and thus less current drain.

Mr. Burnout from outer space,

So does that mean that you have not measured the current draw of the batter while the car is off?

I described several methods in the above post.

If you do that, I think you'll be well on the way to solving your problem.

But then again what does this bumbling fool (me) know.

same thing happened to me.
check the relay at the hatch (pulldown motor)
or the other relays with engine off.

Try taking the hot lead off of the altinator, and see if the car dies then.
Or better yet... hook up your volt meter to the battery and the start unhooking power wire from different locations (alt, starter, fuses) and check the voltage everytime you unhook something.... if your batt dies that quick there should be a huge drain on the batt, and when you find it, the batt voltage should go up a little. ( 11.5 to 12.5 or something like that)
