Lisle Parasitic Drain Testers Lisle parasitic drain testers can provide an easy method for connecting a multimeter to the vehicle electrical system to diagnose hidden battery drain. The replaceable in-line fuses protect both the meter and tester in the event a high current source on the vehicle if left on. The multimeter is bypassed with the switch during connection in case of a power surge. The tester and meter can remain connected until other computer systems shut down， isolating the drain. For convenience， stacking banana connectors are used on the tester.
