• All Rolls-Royce & Bentley models from 1969 to 1980 (8742-41686)

This lead is from the electrical & ignition section in the Rolls-Royce & Bentley parts catalogues for models built between 1965 to 1980.

As with all high-usage engine components, ignition leads wear out over time and need replacing. Integral to the engine’s fuel ignition system, ignition leads are responsible for carrying the electrical current from the ignition coil to the spark plug. Sometimes known as high-tension, or HT, leads (referring to the voltage they carry), each ignition cable encloses a single wire through which the current flows before returning via the opposite battery terminal or negative terminal.

Common symptoms of faulty ignition leads include bad starting, misfiring, rough running, and radio interference. Damage is usually caused by worn-out cable insulation or dirty cable connectors. Left unchecked, this damage could lead to excessive fuel consumption.
