I have some comments:

1) I have never seen it take more than three minutes for all modules to go to sleep, I don't see where he's getting this '1/2 hour' thing.
2) I like the AmpHound, I'd heard conflicting news about how well such products worked but this guy proves this particular product does work.
3) When pulling fuses (which he does not do) you will see odd current readings. Pulling some fuses will cause the current to go UP. STOP, wait three minutes! Pulling some fuses causes some modules to reset and "start over", so wait three minutes to see if the current settles down. This is a disadvantage of the "fuse pulling" method and is an advantage of the AmpHound.
4) This guy explains and then SHOWS YOU how to connect your meter, even if you are not using his $2000 instrument, this is how you connect your multimeter.

This thread will be our standard-issue "how to" for battery drain issues. Sticky it is!
