Fuse 103 powers up a lot of the fuse box under the dash including the accessory delay relay and battery saver relay. It's normal to see a draw on this fuse if you check it within about 45 minutes of turning off the key.
If you hook up the ammeter and leave the doors shut, ignition off etc and look at the meter after about 45 minutes you'll probably find that the draw is gone.
