🔌 Function

The ignition coil receives trigger/power-pack output and steps it up to high voltage so the spark plug can fire under compression.

Common signs of failure:

• Weak or missing spark on one cylinder

• Misfire under load

• Hard starting

• Cylinder drops out when hot

• Cracked coil body or carbon tracking

• Corroded coil terminal

• Spark improves or fails when coil wiring is moved

📦 Condition

• Genuine used part

• Removed from running engine where applicable

• In good working condition unless otherwise stated
