ABSTRACT:
The corresponding opposite end portions of wires at opposite ends of a multi-wire conductor are matched in accordance with this invention with the use of a direct current circuit tester in conjunction with a diode assembly. The diode assembly is connected to the wires at one end of the conductor and the direct current circuit tester is applied to the wires at the opposite end of the conductor according to a specified procedure to identify or match the corresponding opposite ends of the respective wires. The circuit tester comprises a pair of probes, a direct current power source, and indicator means all electrically connected and operable for indicating the presence of an electrically conductive path connected between the probes. A reversing switch is connected to the probes to permit reversing the polarity thereof, with the reversing switch including a handle portion positioned to facilitate readily actuating the reversing switch by someone using the circuit tester.
