General Notes For Repairing The Vehicle Electrical System

CAUTION:
- Wiring harness and connector repairs on vehicle electrical system may only be performed using Wiring Harness Repair Kit VAS 1978.
- Observe appropriate regulations.
- By disconnecting the negative battery connection (opening the circuit), it is possible to safely work on the electrical system. With ignition switched off, disconnect battery Ground (GND) cable.
- Note stickers in vehicle identifying parts under high voltage. Discharge residual voltage before starting work.


- Before commencing repair work, always eliminate cause of damage, e.g. sharp body edges, faulty loads, corrosion.
- If possible, do not loosen grounding straps from the body (danger of corrosion).
