DB Electrical offers precision engineered CDI Modules to power your electrical system. Also commonly referred to as the “Black Box’ or sometimes the “Igniter Box,” CDI Modules are more formally known as capacitor discharge ignition systems. Our CDI Modules store energy until it’s most needed for power and performance. When the system requires a boost in energy, the CDI Module precisely and quickly releases a charge to the spark plug. The end result is smooth and responsive performance of the vehicle you’re riding or driving.

Frequently Asked Questions

Q: What is a CDI Module and what does it do?
A: CDI stands for Capacitor Discharge Ignition. They store energy like a battery and release energy almost instantaneously. That is what makes them perfect for an ignition system. It is the brain that controls the ignition combustion process.

Q: What causes a CDI module to go bad?
A: The CDI is packed full of sensitive electronics. Over time, moisture, heat and vibration will take a toll on the internals of the CDI.

Q: What are the signs of a failing CDI module?
A: The signs for a failing CDI box are similar to many other types of problems. If you experience any of these signs, you’ll want to investigate the condition of your CDI ignition system, but you won’t be able to immediately identify the CDI box as the problem. The CDI box could just be one of several suspects. A failing CDI box can cause difficult starts, rough operations, misfiring, engine stalls and other ignition problems. These common symptoms make CDI diagnosis very difficult. Every component in the system must be checked to be in spec and only the process of elimination will diagnose the specific issue.

Q: What are the other parts associated with the CDI system?
A: Other parts include the stator, hall sensor, flywheel, charging coil and timing mark.
