Visual Check and Contact Pressure Check








3. VISUAL CHECK AND CONTACT PRESSURE CHECK
- Disconnect the connectors at both ends.
- Check for rust or foreign material, etc. on the terminals of the connectors.
- Check crimped portions for looseness or damage and check if the terminals are secured in the lock position.

HINT: The terminals should not come out when pulled lightly.

- Prepare a test male terminal and insert it in the female terminal, then pull it out.

HINT: When the test terminal is pulled out more easily than others, there may be poor contact in that section.
