πŸ”§ How to Use

Relay Test:

  1. Connect the red clip to the vehicle battery positive (+), black clip to negative (-).

  2. Select 4PIN or 5PIN mode based on your relay.

  3. Insert the relay into the corresponding socket.

  4. Press the TEST button.

  5. Green Light = Relay is good. Red Light = Relay is faulty and needs replacement.

Battery Voltage Test:

  1. Connect the red and black clips to the battery terminals.

  2. The digital screen will display the current battery voltage (e.g., 12.6V).

  3. This helps you quickly assess battery charge level and charging system health.

⚠️ Important Notes

  1. Voltage Range: Designed for 12V-24V DC systems only. Do not use on higher voltage circuits.

  2. Connection: Ensure the alligator clips are securely attached to the battery terminals for stable readings.

  3. Relay Selection: Always select the correct pin mode (4PIN or 5PIN) before testing.

  4. Battery Test: The voltage reading is for reference. For a comprehensive battery analysis, a dedicated battery tester is recommended.

  5. Safety: Always follow standard automotive electrical safety procedures when working with vehicle batteries.
