Quickly find, trace, and test vehicle wiring without cutting or scraping insulation. This tool helps you locate wires in tight spaces, identify shorts or open circuits, and safely diagnose electrical faults on DC vehicle circuits. Key benefits Non-intrusive wire tracing: Flexible probe traces wires without damaging insulation, so you can test bundled or hidden wiring without splicing or exposing conductors. Accurate fault detection: Detect short circuits and open breaks in automotive wiring with clear LED indicators on both the transmitter and receiver for reliable visual feedback. Safe, vehicle-ready operation: Works on DC 6–42 V circuits used in cars, trucks, and other vehicles. Built-in surge and overload protection helps protect the tool and the vehicle’s circuits during diagnosis. Easy to use for pros and DIYers: The included transmitter and receiver simplify wire identification and continuity testing; adjustable sensitivity and a flexible probe make this tool practical in constrained locations. Key features and specifications Function: Non-intrusive wire tracing, continuity testing, short and open circuit detection. Components: Transmitter and receiver with LED indicators for status and signal strength. Probe: Flexible probe designed to reach bundles, conduit runs, and behind panels without damaging surrounding components. Sensitivity: Adjustable sensitivity to improve detection in congested wire runs and hard-to-reach areas. Voltage compatibility: Designed for DC 6–42 V circuits (automotive use). Protection: Internal surge and overload protection for safer operation in vehicle electrical systems. Design intent: Professional-grade build for technicians and home mechanics. Typical applications Tracing a single wire inside a multi-wire bundle behind a dashboard without removing panels. Locating a short or open circuit in engine bay harnesses on cars or trucks. Following wiring runs through conduit or behind trim to identify where a break or fault occurs. What you get Transmitter and receiver set with flexible probe, adjustable sensitivity, and LED indicators for clear testing results. Simple to operate, practical in tight spaces, and built for the DC voltage ranges common in vehicles — this cable tracker helps you diagnose wiring problems accurately and without damaging insulation.
