- Quick, out-of-vehicle relay testing checks both the relay coil and switching contacts.
- Automatic testing provides a pass or fail indication and identifies faulty relays.
- Works with 4-pin and 5-pin relays and tests the 3 most popular automotive relay types.
- Simple and efficient operation supports testing of 4-pin and 5-pin relays.
- Uses the vehicle's 12-volt battery as its power source.
The automotive relay tester automatically identifies the pin position, action release time, and relay consistency during every testing phase. A green LED means the relay is functioning normally, while a red LED indicates an abnormal relay.
To begin, attach the black alligator clip to the negative battery terminal and connect the red clip to the positive terminal of the vehicle battery. Once the red LED illuminates, testing can start. The tester is suitable for most general-purpose automotive relays available on the market and automatically determines the pin arrangement of an unknown relay.
Its compact construction also makes this tester convenient to carry and store. It is small and lightweight, measuring 1373cm and weighing 260g. In addition, its patented design makes operation easy wherever you are, delivering accurate results quickly and conveniently.
Overall, this automotive relay tester is a practical and efficient tool for checking your vehicle's relays. Automatic detection and straightforward operation help you locate relay faults quickly and complete the required repairs.
