Wiring
Possible causes
- Loose/oxidised connector
- Cable break at moving parts
- Water ingress
Safe test steps
- Check the harness while flexing (continuity, unpowered).
- Voltage drop across the connector under load.
Workshop reference values
- Voltage drop across one connector under load: < 0.1 V good, > 0.3 V abnormal (rule of thumb).
Repair approach
- Replace connector, repair cable with solder and heat-shrink.
Tools needed
- Digital multimeter (CAT III, fused inputs)
- Contact cleaner, dielectric grease
- Soldering iron, heat-shrink
Safety
- Do not handle exposed live wiring.
