Phillips’ tractor-trailer power check

Updated Mar 23, 2018

Phillips’ Qwik-CheckPhillips’ Qwik-Check is built for quick, easy confirmation of power within the seven-way connection between the tractor and trailer. Designed for integration into the nosebox’s electrical system, the device allows for visual confirmation using color-coded LEDs that light up as each circuit receives power; an unlit light indicates a problem with the associated circuit. The universal unit comes with 12-inch blunt-cut wires and ring terminals to customize installation. Replacement units for the company’s I-Box and Volt-Box noseboxes come with wires precut to length and ring terminals installed.
