Wires With Cross Section Up To 0.35 mm 2, Repairing
When repairing wires with a cross-section up to 0.35 mm2 , new contacts must always be crimped on using the Crimping Pliers - JPT VAS 1978/9A or the Wiring Harness Repair - Crimping Plier - Base Tool VAS 1978/1-2 with the Wiring Harness Repair Set - Crimping Head - JPT VAS 1978/9-1 installed. Due to the low current strengths of these wires in the micro- to milli- range, contacts crimped on incorrectly lead to continuity resistances and cause malfunctions or failure of the respective system. The most frequent applications of these contacts are:
- Heated Oxygen Sensor
- RPM sensor
- Mass Airflow Sensor
By using the Crimping Pliers - JPT VAS 1978/9A or the Wiring Harness Repair - Crimping Plier - Base Tool VAS 1978/1-2 with the Wiring Harness Repair Set - Crimping Head - JPT VAS 1978/9-1 installed, the correct connection between crimp contact, wire and single wire seal is guaranteed. The tool is to be used only for the purpose described.
Contacts in a normal and a gold-plated version are crimped onto repair wires. The same version of the contact that was installed at the factory must always be used for repairs.
Crimping a new contact with single wire seal
-- Insert the Wiring Harness Repair Set - Crimping Head - JPT VAS 1978/9-1 into the Wiring Harness Repair - Crimping Plier - Base Tool VAS 1978/1-2, refer to CRIMPING PLIERS -.35-2.5mm VAS 1978/1A .
-- Place the single wire seal onto the repair wire.
When doing this, the smaller diameter of single wire seal must be facing in the direction of the contact to be crimped on.
-- Open the Wiring Harness Repair - Crimping Plier - Base Tool VAS 1978/1-2 (green body) and insert the repair wire end into the stripping slot of the Wiring Harness Repair - Crimping Plier - Base Tool VAS 1978/1-2.
-- Close the Wiring Harness Repair - Crimping Plier - Base Tool VAS 1978/1-2 completely.
-- Reopen the Wiring Harness Repair - Crimping Plier - Base Tool VAS 1978/1-2 and remove the stripped wire end.
-- Slide single wire seal in direction of stripped wire end until it rests flush with the wire insulation.
-- Insert the new crimp contact into the Wiring Harness Repair - Crimping Plier - Base Tool VAS 1978/1-2 mount.
-- Insert the stripped wire end with positioned single wire seal into crimp contact until it makes contact on "Wire-Stop".
-- Crimp the contact, wire and single wire seal by completely closing the Wiring Harness Repair - Crimping Plier - Base Tool VAS 1978/1-2.
-- Reopen the Wiring Harness Repair - Crimping Plier - Base Tool VAS 1978/1-2 and remove the finished crimped-on contact.
A correctly performed crimp is distinguished by a clean compression of wire and single wire seal in the contact and has an impression on the rear side which identifies that the crimp was performed by a professional using the correct tool.
