Description
The Sealey Open & Short DC Circuit Detector 6-42V is a diagnostic tool designed for tracing electrical faults in DC systems. This two-piece testing system enables automotive technicians and electrical contractors to identify both open and short circuits quickly across low-voltage DC applications up to 42V. The detector operates using a sender unit that attaches directly to the circuit under investigation, whilst the handheld receiver unit traces the wiring to pinpoint fault locations. This non-invasive testing method is particularly valuable for automotive repairs where circuits may be concealed behind trim panels or routed through complex wiring looms, allowing faults to be located without unnecessary dismantling. Suitable for a wide range of DC electrical systems including automotive applications, marine electronics, and agricultural machinery, the circuit detector provides an efficient solution for troubleshooting electrical problems. The unit is supplied complete with two 9V batteries and housed in a protective storage case, making it ready for immediate use and convenient for mobile workshop applications. Features and Benefits: • Two-piece sender and detector system for easy circuit tracing • Works on all DC circuits from 6V to 42V for versatile application • Supplied with protective storage case and batteries for convenience • Ideal for locating faults in concealed automotive wiring systems Specifications: Brand: Sealey Nett Weight: 0.32kg
