🔌 Function

The ignition leads carry high-voltage energy from the distributor or individual coils to the spark plugs. Marine-grade insulation and correctly fitted terminals prevent leakage, crossfire and radio-frequency interference.

Common signs of failure / service requirement:

• Misfire under acceleration or high load

• Visible arcing in darkness or around damp lead boots

• Cracked, hardened or oil-contaminated insulation

• Excessive lead resistance or open circuit

• Rough idle, crossfire or radio-frequency interference
