Lisle 64970 Parasitic Drain Tester
- Replaceable in-line fuses protect both the meter and tester in the event a high current source on the vehicle is left on.
- The multi-meter 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.
- 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.
