The Capacitor Discharge Ignition or CDI box is an important component in the ignition system of a motorcycle, ATV, or other small engine machines. It generates a high-voltage spark that ignites the fuel mixture in the engine cylinder, which powers the machine. The CDI box has several components, including the ignition coil, voltage regulator, capacitor, CDI unit, and wiring harness. In this article, you will learn more about the 6 pin CDI wiring diagram, its components, functionality, and FAQs.
What is a CDI box?
A CDI box is an ignition box that stores an electrical charge until it’s needed to create a spark in your engine. The CDI box is made up of several components, including the ignition coil, voltage regulator, capacitor, CDI unit, and wiring harness. Each component plays a critical role in the operation of the CDI box.
Components of a CDI Box
The following are the components of a typical CDI box:
| Component | Description |
|---|---|
| Ignition Coil | It generates high voltage for the spark plug |
| Voltage Regulator | Maintains constant voltage supply to the CDI unit |
| Capacitor | Stores and releases electrical energy for the spark plug |
| CDI Unit | Controls the timing and spark output of the CDI box |
| Wiring Harness | Connects all the components of the CDI box |
6 Pin CDI Wiring Diagram
The 6 pin CDI box is an important component in the ignition system. It is a standardized diagram that shows how the CDI box should be wired in your machine. Each pin has a specific function, which is important in the operation of the CDI box. The following is a typical 6 pin CDI wiring diagram:
Function of Each Pin in the 6 Pin CDI Box
The following is the function of each pin in the 6 pin CDI box:
| Pin Number | Function |
|---|---|
| Pin 1 | Ignition Coil Output |
| Pin 2 | Pulse Generator |
| Pin 3 | Ignition Timing Advance |
| Pin 4 | Ground |
| Pin 5 | Kill Switch |
| Pin 6 | Battery Voltage Input |
How Does a CDI Box Work?
The CDI box works by storing electrical charge from the battery and using it to create a spark through the ignition coil. The CDI box receives a trigger signal from the pulse generator, which tells it to release the energy stored in the capacitor. The CDI unit then controls the timing and spark output of the ignition coil, ensuring that the spark occurs at the right time.
Types of CDI Boxes
There are two types of CDI boxes: AC-CDI and DC-CDI. AC-CDI boxes use alternating current (AC) from the generator to power the CDI box, while DC-CDI boxes use direct current (DC) from the battery. The type of CDI box you need depends on the type of generator or alternator your machine has.
Common CDI Box Problems and FAQs
Q: What are some common CDI box problems?
A: Some common CDI box problems include failure to start or run, loss of power, rough idle, and misfiring. These problems may be caused by faulty wiring, a damaged CDI box, or other issues in the ignition system.
Q: How do I troubleshoot a faulty CDI box?
A: You can troubleshoot a faulty CDI box by checking the wiring connections, testing the ignition coil and spark plug, checking the pulse generator, and using a multimeter to check the voltage and resistance of the CDI box components.
Q: How do I know if my CDI box is bad?
A: A bad CDI box may cause the engine to stall, misfire, or fail to start. You may also notice a loss of power or poor performance. To diagnose a bad CDI box, you may need to test the ignition coil and spark plug, check the wiring connections, and use a multimeter to check the voltage and resistance of the CDI box components.
Q: Can I replace the CDI box myself?
A: Yes, you can replace the CDI box yourself if you have the tools and knowledge to do so. You may need to refer to the manufacturer’s instructions or hire a professional mechanic to ensure that the replacement is done properly.
Q: How much does a CDI box cost?
A: The cost of a CDI box depends on the brand, model, and type of CDI box you need. Prices range from $20 to $200 or more.
Conclusion
The CDI box is an important component in the ignition system of a motorcycle, ATV, or other small engine machines. It stores electrical energy and releases it to create a spark through the ignition coil. The 6 pin CDI wiring diagram shows how the components of the CDI box should be wired together. There are two types of CDI boxes: AC-CDI and DC-CDI. If you encounter any problems with your CDI box, you can troubleshoot it by checking the wiring connections, testing the ignition coil and spark plug, and using a multimeter to check the voltage and resistance of the CDI box components.
