J 38125-B Terminal Repair Kit
The supplemental inflatable restraint (SIR) system/supplemental restraint system (SRS) requires special wiring repair procedures due to the sensitive nature of the circuitry. Follow the specific procedures and instructions when working with the SIR/SRS system wiring, and the wiring components (such as connectors and terminals).
IMPORTANT:
Do not use the terminals in the kit in order to replace damaged SIR/SRS system terminals unless specifically indicated by the terminal package.
The tool kit J 38125-B contains the following items:
- Special sealed splices - in order to repair the SIR/SRS system wiring
- A wire stripping tool
- A special crimping tool
- A heat torch
- An instruction manual
The sealed splices have the following 2 critical features:
- A special heat shrink sleeve environmentally seals the splice. The heat shrink sleeve contains a sealing adhesive inside.
- A cross hatched (knurled) core crimp provides necessary contact integrity for the sensitive, low energy circuits.
The J 38125-B also serves as a generic terminal repair kit. The kit contains the following items:
- A large sampling of common electrical terminals
- The correct tools in order to attach the terminals to the wires
- The correct tools in order to remove the terminals from the connectors
