Abstract: A kit is provided for making a continuity tester from an existing pliers tool and an existing continuity checker to check electrical continuity of a wire. The kit includes a first sleeve adapted to slip onto a free end of a first jaw of the pliers tool and which includes a protrusion that faces laterally, and a second sleeve adapted to slip onto a second jaw and which includes a pocket for holding the wire while the protrusion is piercing the wire. The first and second sleeves are tubular, and are held on by resilient tabs that frictionally engage the jaws. A connector adapted to frictionally engage the probe of the continuity checker is provided either on the first sleeve or on a third sleeve engagable with the first handle of the pliers tool. In one form, the kit is factory-installed as a permanent part of the pliers tool.
