Eliminates the need for back-probing coil wires and disassembly to test at the coil connector or spark plug.

Designed to test for Kilovolt and Arc Duration output.

Simply press the 9" long antenna probe against the ignition coil. Each time the unit detects a spark firing it will flash the bright LED strobe indicating sufficient kV and flash the green LED indicating sufficient Arc Duration. This allows the technician to determine if the coil is firing the spark plug consistently, intermittently misfring or not at all.
