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.
- Disconnect the battery before replacing.
- Check the condition of the connectors and wiring: the cause is often right there.
