check all grounds, and make sure the alternator idiot light in the dash is working when you turn the key to the "run" positon without the engine running.
do you have a multi meter? if not, why not? it is one of the most useful tools ever invented.
also, a good test light is a good thing to have, as well.
the most logical place to start looking for a curent draw would be an aftermarket stereo installed- especially if you have added external amps. unhook all that crap and see if it still does it.
is the under hood light staying on with the hood shut? dome light always on? radio hooked up so you can listen to it with the key off?

Get a test light and go through all your fuses,with the key off. The one that lights up is a good place to start.

Also check the diode set in the alternator.

With everything in the car switched off, remove the Neg cable from the battery and place a test light (or interior style light bulb) between the Neg battery post and the Neg cable clamp. If your light glows, you have a power drain. The glow may be very dark, so cover the bulb as best you can if ness.
Remove and replace one fuse at a time untill the glowing of the test light stops. When you find the fuse that stops the glowing of the test light, you have found the circuit where the power drain exists.
Disconnect and reconnect the components on that curcuit until you find the culprit.
Your assembly manual may be a big help to you. (UPC 12, D1-D4)

If you have a voltmeter, that would be easier to read. Set it to mA and connect it at battery like BlackoutSteve said.

noname,
It could be the battery itself. Try charging it up and then disconnecting the cables and let it sit for a couple of days. Hook it back up and see if it works. If it is dead, then it probably has an internal short that is running it down.
If its not the battery, you will have to start disconnecting things one at a time to see what is causing the problem.
