Parasitic battery drain test method #1 current draw testing for parasitic battery drain. in a current draw test you watch for a drop in current as you remove each fuse from the fuse box. if you pull a fuse and notice the current drop to less than 50 miliamps, you’ve identified the circuit with the problem. A short circuit – a short circuit can cause a parasitic draw by allowing current to flow through an unintended path. a stuck relay – a stuck relay may continue to draw power even when the ignition is turned off. a parasitic draw can be harmful to the vehicle’s battery and may cause it to go dead if it is not addressed. 3. conduct initial test. pop the hood and get in position. if the hood is equipped with a lamp, make sure to rig the pressure switch or pull the bulb to keep it from interfering with your test.
