What it does

Many electrical faults are a bad connection rather than a failed part, so check grounds and connectors first. Electrical faults often show up as warning lights, rough running or no-start problems, and the right replacement part clears the cause rather than the symptom.

Installation & tips

  • Disconnect the battery before electrical work and check grounds first.
  • Fuses and relays: Cheap to keep spares.
  • Disconnect the battery before you unplug or splice any wiring, and test everything works before you refit trim panels.
