This article describes a tester for sequentially testing the wires of a multiple wire cable. Each wire is tested for open circuit, short circuit, and incorrect connection. The result of the test is visually displayed so that the actual fault and the conductor or conductors involved are easily identified. The tester is comprised of a master unit (Fig. 1) and a slave unit (Fig. 2). The master unit includes a single light source 20 (such as a light-emitting diode (LED)) and a plurality of switches. The switches enable one to select a single wire to be tested. The slave unit includes a plurality of LEDs. Each LED is associated with a particular wire.
