Q » How do you perform a parasitic draw test to find a battery drain?
17 Oct, 2025
A » To perform a parasitic draw test, first ensure the vehicle is off and key removed. Disconnect the negative battery cable and connect a multimeter set to amps between the cable and battery post. Note the reading; a draw over 50 milliamps indicates a problem. Systematically remove and replace fuses while monitoring the meter to identify the circuit causing the drain. Remember, safety first—wear protective gear and consult your vehicle's manual.
