      NOTE:
      • Use a fine wire to prevent damage to the terminal.
      • Do not damage the terminal when inserting the tester lead.
  2. Checking Point for Connector
    1. While the connector is connected:

      Hold the connector, check connecting condition and locking efficiency.

    2. When the connector is disconnected:

      Check missed terminal, crimped terminal or broken core wire by slightly pulling the wire harness.

      Visually check for rust, contamination, deformation and bend.

    3. Check terminal tightening condition:

      Insert a spare male terminal into a female terminal, and then check terminal tightening conditions.

    4. Pull lightly on individual wires to ensure that each wire is secured in the terminal.

  3. Repair Method of Connector Terminal
    1. Clean the contact points using air gun and/or shop rag.
      NOTE: Never use sand paper when polishing the contact points as this may damage the contact points.
    2. In case of abnormal contact pressure, replace the female terminal.
