Sealed splice (1) 6A-3361 Electrical Wire (from 110-8769 Wire Assembly ) (2) 186-3735 Connector Pin (3) 115-8109 Wire Splice (4) 186-3736 Connector Socket (5) Wire from engine or machine harnessThe following procedure explains how to splice the 6A-3361 Electrical Wire to the engine or machine harness. Refer to Illustration 2.
Cut off the damaged R-terminal connector from the machine or engine harness.
Prepare the wires. Refer to Special Instruction, SEHS9615, 01 MAY 93, "Servicing DT Connectors".
Use a 1U-5804 Crimp Tool (12-18 AWG) to secure an 8T-8729 Connector Pin to the end of the 110-8769 Wire Assembly. After the 8T-8729 Connector Pin has been crimped on the wire, insert the connector pin into the socket-end of the 115-8109 Wire Splice. After the connector pin has been inserted into the wire splice, tug on the wire to ensure that the connector pin is locked in place.
Use a 1U-5804 Crimp Tool (12-18 AWG) to secure an 8T-8730 Connector Socket to the machine or engine harness. After the 8T-8730 Connector Socket has been crimped on the wire, insert the connector socket into the pin-end of the 115-8109 Wire Splice. After the connector socket has been inserted into the wire splice, tug on the wire to ensure that the connector socket is locked in place.
Reconnect the R-terminal connector to the alternator. Confirm proper operation.Note: The 8T-8729 Connector Pin and the 8T-8730 Connector Socket can be removed from the 115-8109 Wire Splice with a 4C-4074 Contact Removal Tool .
