FAQ

What exactly is the task / function of the component?
The wiring harness distributes supply voltage, ground, sensor signals and actuator controls within the assembly. It thus defines the electrical connection topology between the motor, peripherals and control station.

How do you recognize a defect / typical symptoms?
Typical symptoms are several simultaneously occurring or sporadic faults, intermittent vibrations, corroded plug connections or localized cable fires. Particularly critical are chafe marks, green discolored conductors and water in sealed connectors.

How do you check / test the component?
Check for continuity, short circuit to earth or neighboring wires and voltage drop under load, pin by pin. In addition, bending radii, chafing protection, branches and the locking of all connectors should be checked visually.

When should it be replaced?
Replacement is indicated if several cable branches are damaged, plug seats are worn out or previous repair points no longer appear to be permanently resilient. In the case of individual localized damage, professional repair may suffice.

How do you check compatibility?
The OEM number, motor or system variant, cable lengths, branch positions, connector set, pin assignment and any optional cables are required. The production status or serial number range can also be decisive.
