The Sealey TA131 Relay Tester is a professional diagnostic tool designed to health test 4 and 5-pin electro-mechanical relays commonly found on modern vehicles. This compact tester provides accurate assessment of relay condition through automated cycle testing, making it an essential tool for automotive electricians and mechanics diagnosing electrical faults. The relay tester features an automated test function that cycles the relay 10 times, comprehensively testing resistance, contacts and consistency throughout each cycle. Clear LED indication provides instant diagnostic feedback, with a red LED signalling if any cycle fails and a green LED confirming the relay is functioning correctly. Powered directly from a 12V vehicle battery via insulated crocodile clips, this tester eliminates the need for separate power sources. The 1400mm flying lead length provides excellent reach when working across engine bays or vehicle electrical systems, whilst the compact 130 x 70 x 35mm module size makes it easy to store in a toolbox or mobile workshop setup.
