Terminated Lead Repair
Terminated Lead Repair
Special Tools
* J-38125-8 - Splice Sleeve Crimp Tool
* J-38125-5 - Ultra Torch
For equivalent regional tools, refer to Special Tools (Tools and Equipment).
Note: All repairs near the engine manifold, turbo engine and all exhaust pipes should follow the High Temperature Wiring Repairs (High Temperature Wiring Repairs) procedures.
Terminated leads are terminals that are crimped onto wires. The terminated lead can be used throughout the vehicle since it is designed for temperatures up to 150°C. The length of the wire is 450 mm.
The DuraSeal splice sleeve has the following 2 critical features:
* A special heat shrink tubing that environmentally seals the splice. The shrink tubing contains a sealing adhesive inside the shrink tubing.
* A cross hatched (knurled) core crimp that provides the necessary contact integrity for sensitive low energy circuits.
1. Use the connector end view to identify the correct terminated lead.
2. The terminated lead package should include a DuraSeal splice sleeve. If not, use the chart to identify the correct part.
3. Open the harness by removing any tape:
Use a sewing seam ripper, or a comparable tool, to cut open the harness, to avoid wire insulation damage.
4. Depending on how many terminals need repairs, cut the terminal and wire back at least 40 mm. Try to keep the harness wire length the same.
If more than one terminated lead is required, stagger the lengths by 40 mm. This helps reduce the bundle size of the wire harness.
5. Use the EL-38125-10 - tool in order to position the DuraSeal splice sleeve in the proper color nest of the splice sleeve crimp tool. The crimp tool has four nests, one for each color.
6. Place the DuraSeal splice sleeve in the nest. Ensure that the crimp falls midway between the end of the barrel and the stop. The sleeve has a stop (3) in the middle of the barrel (2) in order to prevent the wire (1) from going further. Close the hand crimper handles slightly in order to firmly hold the DuraSeal splice sleeve in the proper nest.
7. Insert the wire into the splice sleeve barrel until the wire hits the barrel stop.
8. Tightly close the handles of the crimp tool until the crimper handles open when released.
The crimper handles will not open until you apply the proper amount of pressure to the DuraSeal splice sleeve. Repeat steps 4 and 5 for the opposite end of the splice.
9. Using the J-38125-5 - ultra torch, apply heat to the crimped area of the barrel.
10. Start in the middle and gradually move the heat barrel to the open ends of the tubing:
* The tubing will shrink completely as the heat is moved along the insulation.
* A small amount of sealant will come out of the end of the tubing when sufficient shrinkage is achieved.
