  What Is This Part?

This is the main electrical cable carrying battery power to the starter connection. The starter draws a high current when turning the engine, so the condition of both the cable and its terminal connections matters. This replacement retains original-style terminals and grommets, which are relevant when renewing an ageing installation. It forms part of the starting circuit alongside the battery, starter and earth connections, all of which should be considered when investigating poor cranking.

What Does This Part Do?

• Carries starting current: Provides the electrical supply path from the battery to the starter connection.
• Connects the circuit: Its terminals provide the fixing points for the cable's electrical connections.
• Insulates the conductor: The cable covering separates the live conductor from surrounding components.
• Protects at pass-through points: The grommets help separate the cable from the edges of openings along its route.
  
  Why Replace This Part?

Corrosion, damaged strands or deteriorated terminal joints can increase resistance in a starter cable. Under starting load, this can cause voltage loss between the battery and starter, contributing to slow or intermittent cranking. Cracked, rubbed-through or heat-damaged insulation is another reason to assess the cable for replacement.

Confirm the cause before replacing it: a weak battery, poor earth connection or starter fault can produce similar symptoms. A voltage-drop test under cranking load helps distinguish a cable or connection problem from faults elsewhere. During restoration, inspect the existing cable rather than replacing it solely because of its age.

When to Replace This Part?

• Damaged insulation: Splits, abrasion, exposed conductor or melted areas are visible.
• Corroded connections: Corrosion has damaged a terminal or extends into the cable.
• Loose or damaged terminals: A terminal is cracked, distorted or cannot be secured correctly.
• Confirmed voltage loss: Testing identifies excessive resistance in the cable after its connections have been checked.
• Deteriorated previous repairs: Inspect unreliable joins, damaged ends or poorly protected sections.
• Poor seating: Check displaced or damaged grommets and any resulting cable abrasion during removal or refitting.
  
  Where Is This Part Fitted?

Location: Between the battery supply and the starter connection, forming part of the vehicle's main starting-circuit wiring. Follow the original cable routing and check the supporting clips, pass-through protection and terminal seating during installation.

  FAQs

• Does slow cranking mean the cable has failed? No. Check battery condition, earth straps, terminal connections and the starter before deciding which component needs replacement.
• Can a cable look intact but still have a fault? Yes. Internal corrosion or damaged strands may not be obvious externally; testing under load can help identify excessive resistance.
