Troubleshooting Test Steps Values Results
4. Perform a Pull Test on Each Wire Terminal Connection
A. Ensure that the locking wedge for the connector is installed properly. Terminals cannot be retained inside the connector if the locking wedge is not installed properly.
B. Perform the 45 N (10 lb) pull test on each wire. Each terminal and each connector should easily withstand 45 N (10 lb) of tension and each wire should remain in the connector body. This test checks whether the wire was properly crimped in the terminal and whether the terminal was properly inserted into the connector.
45 N (10 lb)
Result: All terminals pass the pull test.
Proceed to Test Step 5.
Result: A wire has been pulled from a terminal or a terminal has been pulled from the connector.
Repair: Use the 1U-5804 Crimp Tool to replace the terminal. Replace damaged connectors, as required. Verify that the repair eliminates the problem.
