Usage:
Many of the Operational Procedures and Diagnostic Code Procedures in this troubleshooting guide will direct you to check a specific electrical connector. Use the following steps to help determine if the connector is the cause of the problem. If a problem is found in the electrical connector, repair the connector and continue the test procedure.
1. Check Connector Lock Ring Or Allen Screw. Make sure that the connector is properly locked and that the lock ring or allen screw (4mm) is capable of locking the connector together.
2. Perform 10 Pound Pull Test On Each Pin/Wire. Each pin and connector should easily withstand 10 pounds of pull, and remain in the connector body. This test checks whether the wire was properly crimped in the pin, and whether the pin was properly inserted into the connector. Repair as needed.
NOTE: Pins should ALWAYS be crimped onto the wires; NEVER soldered.
3. Visually Inspect Wiring. Look for worn or abraded wires. Check for pinched or damaged harnesses.
4. Visually Inspect Connectors. Verify that pins and sockets are not corroded or damaged. Verify proper alignment and location of pins in the connector.
5. Check Individual Pins And Sockets. This is especially important for intermittent problems. Using a new pin, insert the pin into each socket one at a time to check for a good grip on the pin by the socket. Repeat for each pin on the mating side of the connector, using a new socket for the test.
