of the most common automotive relays

 The tester will check for the proper functioning of the relay contacts by connecting

the car battery (11V--15V) to the relay coil

 The tester will watch the pin configuration, the time to contact closure and opening,

consistency of the relay during each test session, the tester will light the green LED
