The tester will check whether the relay contacts are working properly by connecting the car battery (11V-15V) to the relay coil. The tester will observe the pin configuration, contact closure and disconnection time, and relay consistency during each testing process. If all pass during the testing process, the tester will light up the green LED. If not, the red LED will light up. Usage: 1.
