Got a multimeter? Put it on the positive and negative terminals - NOT THE CLAMPS -on your battery. Get a reading. Now disconnect the positive clamp. Put the positive probe on the positive post, and the negative probeon the positive clamp. You should get almost no current.

If you got the same as when you got your first reading, then pull any fuse, check the post-to-clamp reading again, replace, and try another fuse, til you find the fuse/circuit that is pullin' the juice from the battery post to the battery clamp.

This test assumes that the short is NOT between the battery and the fuse block. If it is, you got a meltdown in the waiting, and you better get some marshmallows, and a LOOOOOOONG stick.

Depends on if you got an analog or digital meter. You're lookin' for 12V, D/C, probably between 1-5 amps. Any more would have made smoke. Might be a selectorswitch on the multi-meter for 0.0 - 1.0 amps, another for 1 - 10/25 amps; the first setting might give you a couple of 'pegged' readings. Make a note of which fuse pulls give you those peggings, THEN check each of THOSE again at the second selector switch setting.

That should tell you which circuit is drawin' the battery's juice...

Anything more than .5 amps will drain your battery down pretty quick.

Have you had a load test done on the battery?
