The Automotive Short and Open Finder is designed to identify and trace wires and cables without damaging insulation, and to locate short and open circuits in electrical systems. The set includes a Sender and a Receiver with a 7 inch flexible probe, allowing tracing inside bundles, conduits, behind panels, under carpets or upholstery. Key benefits - Efficient wire tracing without cutting or stripping insulation, ideal for locating shorts and open circuits in complex wiring. - Flexible reach: 7 inch probe enables access to wires inside congested areas, behind panels, and through tight spaces. - Clear status indication: Transmitter and receiver LEDs show open or short circuit conditions for quick, accurate diagnosis. Open circuit locating - Powered by two 9V batteries, it detects open circuits and immediately indicates their location. - Helps locate short circuits, open connections, broken wires and current leaks. - LED indicators on both transmitter and receiver display open or short conditions for easy verification. Short circuit checking - Useful for finding intermittent problems by flexing wires or connectors and listening for a change in the receiver tone. - The flexible probe aids in reaching wires in hard-to-access or congested places. Compatibility and use cases - Works on DC 6–42 V circuits, covering a wide range of vehicles and equipment. - Suitable for automobiles, trucks, tractors, boats, and RVs, as well as other 6–42 V DC systems. Typical scenarios - Diagnosing a hidden open circuit behind a dashboard or in a wiring harness. - Tracing a suspect wire through a vehicle’s conduit or behind carpeting. - Locating intermittent faults in boat or RV electrical systems where space is tight.
