CDI unit for Suzuki Let's scooters. The electronic unit controls the ignition coil and determines the moment the spark appears at the spark plug.
Signs of a fault are a missing or weak spark, misfires, and being unable to start the engine with a good spark plug and coil. Before replacement, check the wiring and contacts.
- Compare the number and position of the contacts with your connector.
- Make sure the ground is securely connected to the frame.
- Also inspect the neighboring parts of the assembly: they often wear out together.
