Draw test is fairly easy to do. All it takes is a test light. With the ignition off, disconnect your negative battery cable and attach the test light clip to the cable. Touch the probe to your negative terminal and the light should glow. The brightness of the light represents the amount of draw on your system. Now, have a friend start pulling fuses one by one and watch what happens to the light. When you see a signicant drop in brightness that is most likely the offending circuit. Remember, there will always be some level of draw on the battery and when some fuses are pulled there will be just a slight drop in brightness. The most likely suspect is any aftermarket electrical equipment that has been installed on the car. You can also utilize a multi-meter to perform this test in lieu of the test light.
Update: As fuses are pulled, they should be re-installed as you go. Remember, there are also fuses on the driver side end of the dash panel.
