🚗Automotive Relay Tester Tool

Keep Your Automotive Relay In Check On The Go!

The tester will automatically detect 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, the relay is normal; if the red LED light is on, the relay is abnormal.

First, clip the alligator clip of the tester to the car battery, the black clip to the negative pole, and the red clip to the positive pole. When the red LED light is on, it means the tester can start the test. Check the relay before testing. Select the appropriate socket according to the pins, insert the relay into the sockets, press the "Test" button, and the tester will automatically detect the pin position of the unknown relay.
