Phillips Industries has introduced the Qwik-Check, a device that confirms power within the seven-way connection between the tractor and trailer. Designed for integration into the electrical system of the nosebox, it eliminates the immediate need for a continuity tester, visually confirming an electrical signal from the tractor to the trailer, the company says.

With the tractor turned on, and power supplied to the seven-way connection, the color-coded LED lights of the Qwik-Check will light up as each circuit receives power. Each light is an indication that power to the correlating circuit is reaching the seven-way connection. If a light does not come on, it indicates that there is a problem with the associated circuit and further investigation is warranted.

The Qwik-Check is currently offered for universal installation on any nosebox, or as a readily available replacement for units already installed on the i-Box or Volt-Box noseboxes. The universal unit comes with 12-in. blunt cut wires and ring terminals to customize installation. Replacement units come with wires pre-cut to length and ring terminals already installed.
