In my experience, aftermarket accessories cause more parasitic draw problems
than anything else in the car, with aftermarket alarms being the most common
culprit.

I have a nice Snap-On test light but I can't remember ever using it. A test
light's biggest shortcoming is that it will indicate the presence of voltage
but does not give an indication of what that voltage is. For example, 9
volts is enough to illuminate the test light but not enough to start the
car. I much prefer a volt meter for diagnosis.

Pulling the fuses in combination with a volt meter or test light is an old
trick for finding identifying the circuit with a parasitic draw. Once the
circuit is identified, then you have to find out what loads are on the
circuit and start checking each load. Since aftermarket accessories are the
most common cause of excess draws, I start looking there.
