Beergardens is correct. Connect amp meter in series, or I just use a jumper wire until I am ready to watch the draw. My meter times out after several minutes and it will open the connection when it does. You do not want to break the connection. Let it sit undisturbed for an hour so the modules go to sleep. It shouldn't draw more than about .050 amp (50 milliamps) after this. You want the doors and hood open so you can disconnect fuses to isolate the draw. Just use a small screwdriver to latch the door latches fully to simulate the doors being closed.
