About this item

  • 12V 24V Automotive Relay Tester: Suitable for most general-purpose automotive relays on the market. When testing relays, connect this relay tester to the vehicle's 12V or 24V battery. When testing 12V relays, connect it to a 12V battery. When testing 24V relays, connect it to a 24V battery. (Note: If the voltage does not match, normal testing cannot be performed.)
  • 4-Pin and 5-Pin Relay Test: When testing a 4-pin relay, set the switch to 4PIN (↑); when testing a 5-pin relay, set the switch to 5PIN (↓). This relay diagnostic tool is designed to test normally open and normally closed relays（NO/NC）. The testing process is safe, reliable, and will not damage the relay’s internal circuitry.
  • Fast Operation : First, clip the alligator clip of the tester to the car battery, the black clip on the negative pole, and the red clip on the positive pole. When the red LED light is on, the tester is ready to start the test. Then adjust the 4 Pin/5 Pin switch to match the number of pins on the relay. Select the appropriate socket according to the relay pins and configuration and insert the relay into the socket. Press the "Test" button, and the tester will automatically begin to operate the relay several times while checking all operations of the relay.
  • Easy to Use : The OBDResource relay tester will automatically detect the pin position. If the tester lights up the green LED light, the relay is normal; if the red LED light is on, the relay is abnormal.
  • Reliable Automotive Relay Diagnostic Tool: Whether you're a DIY enthusiast or a mechanic, this 12V 24V car relay tester can help you quickly identify relay problems to keep your vehicle running smoothly.
