LISLE Parasitic Drain Tester LS64970

Provides an Easy Method to Connect a Multimeter to the Vehicle Electrical System to Diagnose Hidden Battery Drain.

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. This allows voltage to be measured on various locations on the vehicle during the drain test, using standard test leads.
