ABSTRACT:
An electrical continuity test system with a tester and a remote probe. The tester includes circuitry for creating a pulsed current, an output for connection to a local end of a first test conductive element, to inject the pulses into the first test conductive element, an input for connection to a local end of a second test conductive element, and a visual and/or aural indication when the injected pulses are present on the second test conductive element. The remote probe includes an input for connection to a remote end of a first unidentified conductive element, an output for connection to a remote end of a second unidentified conductive element, a first visual and/or aural indication when the first unidentified conductive element is the first test conductive element, and a different visual and/or aural indication when the first unidentified conductive element is the second test conductive element.
