What it does

Electrical parts carry power and signals around the car. 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.
• Put the new part next to the old one and compare the shape, mounting points and connections before you install it.
• Disconnect the battery before you unplug or splice any wiring, and test everything works before you refit trim panels.
