M13 is only one of the IOD fuses. The white fuse holder, with J13 in it, is the main IOD fuse that will cut power to the individual IOD fuses.
One thing I found out while testing mine is you get a higher reading for a little while after disconnecting and reconnecting the battery. This includes disconnecting and putting an ammeter in series. Lots of things power up when the battery is initially reconnected, then power down after a while.
I use a clamp-on meter to test for draw, and make sure I haven't opened and closed a door for at least 15 minutes.
If you have a hood alarm switch, make sure that is depressed for a while before you take readings.
