🔌 Function

  

The CDM stores ignition energy and fires the spark plug from trigger and stator input, combining ignition module and coil functions in one assembly.

  

Common signs of failure:

  

• No spark on one cylinder

• Weak or intermittent spark

• Engine misfire

• Hard starting

• Spark drops out when hot

• Loss of power under load

• Cylinder fault follows the CDM when swapped

• Burnt, cracked or corroded CDM connector or lead

  

📦 Condition

  

• Genuine used part

• Removed from running engine where applicable

• In good working condition unless otherwise stated
