Tester willwatch the pin configuration,the time to contacts closure and opening,consistency of the relay during each test session, Tester will light theGREEN LED if all passed during the test session,if not light the REDLED.Introduction:1.Connect the power leads to the car battery --black alligator clip tonegative terminal, red alligator clip to positive terminal.2. Tester is powered up when the LED illuminates in RED.3.Check the relay before plugging into the tester. If it's a 4 pinrelay,select"4 pin" on the tester.If it's a 5 pin relay, select"5 pin"onthe tester.4. Plug in the relay into one of the three receptacles.5. Press the "TEST" button.6.Tester will check the pin configuration of the unknown relay. Testerwill light the RED LED if the unkonwn relay is not the same to the mostof common automotive relaysor the pin of the unknown relay is destroyed.7.Testerwill open and close the relay 10 times for testing the time to contactsclosure and opening if the pin configuration of the relay is right.Tester will light the RED LED immediately if the time is overtime.8.Tester will check the consistency of the relay after testing the timeto contacts closure and opening ten times. Tester will light the GREENLED if the test passed, if not light the RED LED.9. Disconnect power leads from the car battery and remove relay from the tester.Attention:1. The car battery must be 12V battery, and the voltage of the battery is among 11V-15V.2. Ideal for coil resistance above 20 ohms.Package Included:1 xCar Relay Tester
