• Universal Automotive Circuit Breaker Finder：Designed for 6V to 42V low-voltage electrical systems, compatible with cars, trucks, trailers, RVs, motorcycles and more. The EM415PRO wire tracer excels at locating broken, damaged, short-circuited and open-circuit wires. Featuring high precision and humanized operation, this circuit tracer is an essential must-have tool for every automotive repair toolbox.
• Accurate Short & Broken Wire Detector Tool：Under the CONT mode of the continuity tester, connect the red and black clips to both ends of the tested wire respectively. A steady green light indicates good circuit continuity or a short circuit condition; if the green light stays off, it means an open circuit fault occurs. It helps you quickly judge wire status and troubleshoot circuit problems.
• User-Friendly & Flexible Design：Equipped with a 7-inch flexible probe, this automotive circuit tester, easily accesses wires in narrow and cramped spaces. It can trace cables behind walls, under carpets and inside wire harnesses without damaging wire insulation. Built-in clear tone prompt and bright LED indicator simplify the identification of open and short circuits, and the adjustable sensitivity enables precise positioning of wire paths.
• Easy & Simple Operation：Simply connect the transmitter in series to the circuit or target wire, then scan the circuit with the flexible probe of the tracer to quickly locate fault points, including connectors, lamp sockets, blown fuses, broken wire connections and other problematic positions. Adjustable sensitivity ensures stable and effective wire tracing in various usage scenarios.
• Wide Compatibility & Multi-Purpose Use：Ideal for DIY enthusiasts, automotive mechanics and professional technicians, it enables fast continuity checking and breakpoint diagnosis of various cables and wires. It works perfectly for all DC 6V-42V circuits, widely applicable to automobiles, trucks, tractors, boats, RVs and other electrical equipment.
