Visual check and contact pressure check

  1. Disconnect the connectors at both ends.
  2. Check for rust or foreign material, etc. on the terminals of the connectors.
  3. Check crimped portions for looseness or damage and check if the terminals are secured in the lock position.
    The terminals should not come out when pulled lightly.
  4. Prepare a test male terminal and insert it in the female terminal, then pull it out.
    When the test terminal is pulled out more easily than others, there may be poor contact in that section.
When testing a gold-plated female terminal, always use a gold-plated male terminal.
When the test terminal is pulled out more easily than others, there may be poor contact in that section.
