Yeah, basically start taking out fuses, stick the black terminal in one side, the red in the other (doesn't matter if you get it backwards, it will just read it as (-) ) Switch to current (A) and check for a draw. Go through all your fuses until you find which one has a significant draw on it (some of them might have a couple of milliamps if there is something that requires memory on that circuit.) Then you can start checking whats on that circuit.
