Provides an easy method to connect a multimeter to the vehicle electrical system to diagnose hidden battery drain. Features: Replaceable in-line fuses protect both the meter and tester in the event a high current source on the vehicle is 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. As a convenience, stacking banana connectors are used on the tester.
