It could be a bad battery.

With everything turned off, pull a battery cable off the battery, and connect a DC volt meter between the battery and the cable. If you get a reading you have something using power. If you don't have a meter a cheap test light might do the trick.

With everything turned off the meter should read zero. If it reads zero I suspect your battery.

If it reads above zero start pulling fuses one at a time and checking the meter. If it goes to zero when you pull a fuse, the circuit related to that fuse in the problem.

It's true. I really don't do anything but browse the Internet looking for trouble...
