Key Features:
✨ Quick Go/No-Go Testing – Tests relay pin configuration, time to contact closure/opening, and consistency over multiple cycles.
✨ LED Indicator Feedback – Green LED lights when the relay passes all tests; Red LED signals failure or incorrect pin configuration.
✨ Supports 4-Pin and 5-Pin Relays – Selectable settings ensure compatibility with most automotive relays.
✨ 10-Cycle Relay Test – Opens and closes the relay 10 times to check proper timing and consistency.
✨ Easy to Use – Simply connect to a 12V car battery with included alligator clips, select relay type, plug in the relay, and press “TEST.”
✨ Durable & Reliable – Suitable for relays with coil resistance above 20 ohms; powered directly from the car battery (11–15V).

How to Use:

  1. Connect the red alligator clip to the positive terminal and black to the negative terminal of a 12V car battery.

  2. The tester powers on when the RED LED lights up.

  3. Select the relay type: 4-pin or 5-pin.

  4. Plug the relay into one of the three tester receptacles.

  5. Press the TEST button.

  6. The tester will check the pin configuration. If incorrect or damaged, the RED LED lights.

  7. The tester will cycle the relay 10 times to check timing and consistency. Any failure during testing lights the RED LED immediately.

  8. If all checks pass, the GREEN LED lights.

  9. Disconnect the power leads and remove the relay after testing.
