Couldn't seem to know the details and condition of your electrical relay?
Want to prevent your car relay to go faulty without warnings?
Relay Tester is the best choice that you can go for.

Can quickly detect whether your relay is normal.
Easy to use, suitable for general-purpose automotive relays on the market.
When testing, it needs to be connected to the car's 11V-15V battery.

Note:
1. The car battery must be a 12V battery, and the battery voltage must be between 11V-15V
2. The applicable coil resistance is preferably above 20 ohms.

Function: 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.

Operating Instructions: 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, 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 sockets, press the "Test" button, and the tester will automatically detect the pin position of the unknown relay.

Automatic Detection: The tester will automatically detect the pin position of the unknown relay. When the relay is not a general-purpose relay on the market or the tester is damaged, it will turn on a red LED. When the pin setting is correct, the tester will open and close 10 times to detect the release time of the action. When the detection time is too long, the tester will light up the red LED light.
