NUT-SPECIAL 1315915 - Caterpillar

Refer to Illustration 44.The 8T-8729 Connector Pin (21) and the 8T-8730 Connector Socket (20) are designed to accept only one 16 or one 18 AWG sized wire.Do not insert multiple wires of a smaller wire size. An incorrect wiring method would be to place two 24 AWG wires in one of the connectors.The 9W-0852 Connector Pin and the 9W-0844 Connector Socket are designed to accept only one 14 AWG sized wire. Do not insert multiple wires of a smaller wire size. An example of an incorrect wiring method would be to place two 20 AWG wires in one of the connectors.Electrical Connectors - Check
Ensure that the connector is properly locked. Also, ensure that the two halves of the connector cannot be pulled apart.
Verify that the latch tab of the connector is properly latched. Verify that the latch tab of the connector is fully latched.Expected Result: The connector will securely lock. The connector and the locking mechanism are without cracks or breaks.Results:
OK - The connector will securely lock. The connector and the locking mechanism are without cracks or breaks. Proceed to the following section.
NOT OK - A problem exists with the connector.Repair: Repair the connector or replace the connector, as required.STOP.Electrical Connector Contact - Pull Test
Each connector contact should withstand 45 N (10 lb) of pull. Each wire should remain in the connector body. This test checks whether the wire was properly crimped in the contact and whether the contact was properly inserted into the connector.The DT connectors use an orange wedge in order to lock the terminals together.Check in order to ensure that the orange wedge is not missing and that the orange wedge is installed properly on the DT connectors.Note: A crimp tool should always be used in order to crimp wires on connector contacts. Do not solder the terminals. Use the proper crimp tool.Expected Result: Each connector contact should withstand 45 N (10 lb) of pull. Each wire remains in the connector body.Results:
OK - Each connector contact withstands 45 N (10 lb) of pull. Each wire remains in the connector body. Proceed to the following section.
NOT OK - A problem exists with the connector.Repair: Repair the wiring or replace the connector contact.STOP.Electrical Wires - Insulation Check
Carefully inspect each wire for signs of abrasion, nicks, or cuts. The following areas are locations that should be checked:
Exposed insulation
Points of rubbing wireCheck all of the hold down clamps for the harness in order to verify that the harness is properly clamped. Also check all of the hold down clamps for the harness in order to verify that the harness is not compressed by the clamp. Pull back the harness sleeves in order to check for a flattened portion of wire. The flattened portion of wire is caused by the clamp that holds the harness.Expected Result: The wires are free of abrasion, nicks, or cuts and the harness is properly clamped.Results:
OK - The wires are free of abrasion, nicks, or cuts and the harness is properly
