Designed for technicians and DIYers, it couples fast, repeatable testing with an included relay puller so you can remove and inspect relays without prying or damaging sockets. Note: not intended for use with all BMW relays.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I run a relay test with this tool?\u003c\/h3\u003e\n\u003cp\u003eTesting is straightforward: clip the black and red alligator clips to the battery negative and positive terminals, select the correct 4-pin or 5-pin setting, insert the relay into the matching socket, and press Test. The unit automatically cycles the relay several times and evaluates contact switching, release timing, and coil consistency.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eConnect clips: red to positive, black to negative\u003c\/li\u003e\n  \u003cli\u003eSelect 4-pin\/5-pin switch to match relay type\u003c\/li\u003e\n  \u003cli\u003eChoose the appropriate socket for relay pin configuration\u003c\/li\u003e\n  \u003cli\u003ePress Test — LEDs indicate pass (green) or fail (red)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat relays and battery conditions does it support?\u003c\/h3\u003e\n\u003cp\u003eThe tester works with most general-purpose automotive relays whose coil resistance is ideally above 20 ohms and that operate on a 12V system.

If you service 12V cars, trucks, or light equipment and need a portable, easy-to-use relay diagnostic that flags intermittent faults and timing issues, this kit provides a pragmatic, time-saving solution. Remember to verify relay compatibility and battery voltage before testing; some BMW relays may not be supported.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will this tester work on 12V car relays?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes—works with most 12V automotive relays when battery voltage is between 11V and 15V and coil resistance is preferably above 20 ohms.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I test BMW relays with this unit?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Some BMW relays are not supported; the tester is not intended for use with all BMW relay types.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Sound Troubleshooting","offers":[{"title":"Default Title","offer_id":48081073832094,"sku":"B0DSM43JZV","price":77.95,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/sound-troubleshooting-front-view-tester.jpg?v=1785795974","url":"https:\/\/northtrailauto.ca\/products\/sound-troubleshooting-12v-handheld-relay-tester-with-puller-clips-pocket-diagnostic-tool-with-leds","provider":"North Trail Auto","version":"1.0","type":"link"}
