Wire Break with Single Repair Point

Special tools, testers and auxiliary items required

• Wire Stripper (VAS 1978/3)

• Crimping Pliers 0.35 mm2 - 2.5 mm2 (VAS 1978/1A)

• Hot Air Blower (VAS 1978/14A)

• Shrink Element For Hot Air Blower (VAS 1978/15)

Repair Point With Single Crimp Connection





- Free up the wire to be repaired (approximately 20 cm (8 in.) on both sides of the repair point).

- If required, remove wiring harness wrapping using a folding knife.

- Cut out the damaged wire section using (VAS 1978/3).






• If, by cutting out the damaged wire section, both ends of the vehicle-specific single wire are too short for a repair using a single crimp connection, insert a repair wire section of matching length with two crimp connections, refer to => [ Wire Break with Dual Repair Point ] Wire Break with Dual Repair Point.

- Strip 6 to 7 mm (0.25 in.) of insulation on the ends of the wires using the (VAS 1978/3).






- Slide crimp connection onto both stripped wire ends of vehicle-specific single wire and crimp them using (VAS 1978/1A).






• Always be sure to use the correct crimping slot for the crimping connection used. Refer to => [ Crimping Pliers with Insert ] Crimping Pliers with Insert.

• Do not crimp wire insulation.

After crimping, crimp connections must be heat-shrunk using the (VAS 1978/14A) to prevent moisture penetration.

- Put (VAS 1978/15) onto (VAS 1978/14A).

- Heat crimp connection using (VAS 1978/14A) lengthwise from center outward until it is sealed completely and adhesive comes out the ends.







When heat-shrinking crimp connections, be careful not to damage any other wiring, plastic parts or insulating material with the hot nozzle of the (VAS 1978/14A).

Always read the Operating Instructions that come with the (VAS 1978/14A) !

• Make sure that crimp connections do not lie directly next to each other when several wires need to be repaired. Arrange crimp connections at a slight offset so that the circumference of the wiring harness does not become too large.






• In the event the repair point was previous taped, this point must be taped anew with yellow insulating tape after repairs.

• Secure the repaired wiring harness with a cable tie to prevent flapping noises while driving.
