Sounds like you have a parasitic draw on the battery. You can use a DVOM and connect it to the battery with the car off and see if there is any kind of draw on the battery. You will have to hook it up in series with the battery and have it on the amps setting not voltage. You will be looking for an obvious amperage draw on the battery.

If you see that there is an amperage draw, then you can start by pulling fuses one by one "make sure to note where each fuse goes and don't put any back until your done with the test". Do this until the draw goes away. This will tell you which ever system is responsible for causing the problem.

I think around 20 millieamps is normal, anything over that something is drawing power. And like coryd21 said, just start pulling fuses until it drops. Good luck

Yeah my red optima kept dying over night finaly drove my car at night. Yep the lc 1 wideband gauge was staying on with the key off. So hopefully its something really stupid like that.
