Prepackaged Wiring Repair Sets
Prepackaged Wiring Repair Sets
Included with the the Electrical Repair Kit IV are a variety of wiring repair sets. These sets contain various pre-crimped wiring connectors on assorted gauge wire lengths for simple splice connection repair into a wiring harness.
The repair kits also contain:
1. Various gauge lengths of wire with precrimped connectors.
2. In-line splice connectors.
3. Heat shrink tubing.
When used correctly the in-line splice connectors provide a BMW factory approved wire crimp. Use the correct size nest in the crimper tool and connect one side of the in-line crimp with the wire.
Slide a piece of heat shrink tubing on the wire and crimp the other side of the in-line connector.
Use a heat gun to shrink the tube around the splice connector to provide a moisture resistant seal.
Part numbers for the wire sets or any component of all four electrical repair kits can be reordered from:
- The P/N reference card inside each repair kit.
- Special tools microfiche.
- The Electrical Repair Kit 1-4 component catalog (SD 92-036).
As new connectors are developed for new vehicles, the repair kits will be announced by Service Information bulletins and sent to dealerships via automatic tools shipment.
Soldering Connections
In the event that a wiring connection must be soldered in a vehicle's electrical system, there are certain procedures which must be followed. Improper soldering will result in poor electrical connections or damage to electrical components.
SAFETY: Adhere to the following basic guidelines when preparing to solder.
- Safety glasses must be worn.
- Disconnect vehicle battery.
- Cover vehicle trim surfaces.
- Exercise your common sense.
- Provide adequate ventilation, it's the best safety precaution!
Soldering Preparation and Procedure
- The wire insulation must be stripped to expose an adequate amount of bare wire (not too little-not to much.)
- The wires and or connectors must be clean and free of grease, dirt, wax, etc.
- A thin coating of rosin core flux must be applied to the soldering connection.
- Have enough 60/40 (tin/lead) general electrical solder on hand prior to starting.
- If heat transfer to a heat sensitive component is possible use "heat sinks".
- Use a soldering gun tip that is the right size for the job. Do not use an overly large tip which could melt wire insulation and block your view of what is being soldered.
- The soldering tip must be "tinned". This means to keep a thin layer of solder on the tip at all times during soldering. This will transfer the heat quickly and allow the solder to flow easily into the joint being soldered.
- Preheat the wires or connector. Introduce the solder into the joint not the soldering tip.
- When the solder starts to flow allow it to infiltrate the joint only for a moment. Almost simultaneously, pull the tip off of the joint to prevent overheating.
- A properly soldered joint will be smooth, shinny, and even surfaced.
