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.
- 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.
