Girlfriends car has a parasitic drain. Whats a good/easy way to test for it?

All i have is a DMM for testing really, a fluke.

Can i test the resting voltage of the battery, and start pulling fuses until there is a voltage change?

disconnect the negative battery cable and set your meter to 10 amps or less then hook positive dmm lead to neg battery post and neg lead dmm to ground terminal you removed from battery then as long as you have less than 1 amp draw set meter to 2 amp or less and start pulling fuses til you find the circuit that is causing it. if you have never done this before its gonna be a huge pain. i am a retired ase tech and some cars are just fking goofy on electrical to figure out.

hope this helps?
