Connector Inspection Service Points




VISUAL INSPECTION
- Connector is disconnected or improperly connected
- Connector pins are pulled out
- Due to harness tension at terminal section
- Low contact pressure between male and female terminals
- Low connection pressure due to rusted terminals or foreign matter lodged in terminals




CONNECTOR PIN INSPECTION
If the connector pin stopper is damaged, the terminal connections (male and female pins) will not be perfect even when the connector body is connected, because the pins may pull out of the back side of the connector. Therefore, gently pull the wires one by one to make sure that no pins pull out of the connector.

MB991219: Inspection Harness (contained in MB991223 Test Harness)




Use special tool, MB991219, to inspect the engagement of the male pins and female pins. [Pin drawing force: 1 N (0.2 pound) or more]
