Automotive Relay Tester for 12V Auto Relay Diagnosis

The handheld 12V relay tester is a versatile and efficient tool designed to quickly and easily check the relays of most modern vehicles. With its user-friendly features, this tester allows for a seamless and hassle-free diagnostic experience.

The tester's easy-to-use functionality is a standout feature. It automatically detects the pin position, the release time of the action, and the consistency of the relay in each test phase. If the tester lights up the green LED light, it indicates that the relay is functioning normally; if the red LED light is on, the relay is abnormal.

To operate the tester, simply clip the alligator clip to the car battery, with the black clip on the negative pole and the red clip on the positive pole. When the red LED light is illuminated, it signifies that the tester is ready to commence the testing process. Before testing, it is essential to check the relay itself.

The tester is designed to be compatible with a wide range of general-purpose automotive relays on the market. During the testing process, it is necessary to ensure that the car's battery is a 12V battery, with a voltage ranging between 11V-15V. Additionally, the applicable coil resistance should preferably be above 20 ohms.

The compact design of the automotive relay tester makes it easy to carry around for on-the-go jobs or for convenient storage. Its small size allows for easy use no matter the location, ensuring that the diagnostic process can be performed efficiently and with minimal hassle.

The tester's patented design is a testament to its simplicity and speed. Users can quickly and easily obtain the results they need, making it an invaluable tool for mechanics, technicians, and car enthusiasts alike.

In conclusion, the handheld 12V relay tester is a versatile and user-friendly tool that simplifies the process of checking the relays in modern vehicles. Its automatic detection capabilities, compatibility with a wide range of relays, and compact design make it an essential addition to any automotive toolkit.
