You need to test your electrical system for parasitic draws; requires putting a digital multi meter between the + post on the battery and the cable, letting the normal draw fall off (1 hr.) if you see more than 40-60 milliamp's, you have a drain. Then you pull one fuse at a time until it drops into range. Last fuse pulled is the circuit with the drain on it.

Good luck.
