How to measure Milliamps Im still having the battery drain problem overnight, next step to measure the ma and start pulling fuses to see where the juice is going. Can anyone tell me how to do this?
Get one of these:

And put it in to current mode (to measure amperes). Pull your positive battery cable off and put the meter's leads in series with the positive battery cable (somehow, affix one meter lead to the battery, and affix the other meter lead to the battery cable).
Then you will be measuring current. Check the meter after each fuse you pull. When it drops... there's your culprit.

Watch the polarity of your meter. Red lead goes to battery (+) terminal and black lead to the cable. Radio shack has small jumper wire with an alligator clip on each end. Might help you attach the leads if you don't have someone to pull fuses while you hold the meter.
