CDI or Capacitor Discharge Ignition is an electronic ignition system that is used in most of the small engines like motorbikes, ATVs, scooters, and many others. This electronic system replaces the traditional mechanical contact breaker and distributor. It uses a capacitor to store and discharge the energy to create a spark that will ignite the fuel in the engine.
The 5 wire CDI box is a type of CDI system that has five wires connected to it. The CDI box is connected to the stator, which produces the electricity required to power the ignition system. In this article, we will discuss the wiring diagram of the 5 wire CDI box in detail.
Wiring diagram
The wiring diagram of the 5 wire CDI box consists of five wires that are color-coded. Each wire has a specific function and connects to a specific component of the ignition system.
Wire 1: Red
The Red wire is the positive wire that connects to the battery’s positive terminal. This wire provides power to the CDI box and the rest of the ignition system. It carries the voltage required to charge the capacitor and to create the spark.
Wire 2: Black
The Black wire is the negative wire that connects to the battery’s negative terminal. This wire completes the circuit and provides the ground to the CDI box.
Wire 3: Green
The Green wire connects to the stator’s trigger coil, which produces the voltage required to charge the capacitor. When the trigger coil’s magnet passes by the coil, it produces a voltage spike that triggers the CDI box to create a spark.
Wire 4: Yellow
The Yellow wire connects to the ignition coil, which amplifies the voltage and creates a high-intensity spark. It is also responsible for providing the spark timing, which ignites the fuel at the correct time.
Wire 5: Blue
The Blue wire connects to the kill switch, which is used to stop the engine. When the switch is turned off, it grounds the Blue wire and shuts down the ignition system.
FAQ
| Question | Answer |
|---|---|
| What is a CDI box? | A CDI or Capacitor Discharge Ignition is an electronic ignition system that replaces the traditional mechanical contact breaker and distributor. It uses a capacitor to store and discharge the energy to create a spark that will ignite the fuel in the engine. |
| What is a stator? | A stator is a component of the engine that produces the electricity required to power the ignition system. It consists of a coil of wire that is stationary and produces an alternating current (AC) when the engine is running. |
| What is the function of the ignition coil? | The ignition coil amplifies the voltage and creates a high-intensity spark that will ignite the fuel in the engine. It is also responsible for providing the spark timing, which ignites the fuel at the correct time. |
| What is the purpose of the kill switch? | The kill switch is used to stop the engine. When the switch is turned off, it grounds the Blue wire and shuts down the ignition system. |
| What happens if the CDI box fails? | If the CDI box fails, the engine will not start or run. The spark created by the ignition system will be weak, or there will be no spark at all. The CDI box can be tested with a multimeter or replaced if it is faulty. |
In conclusion, the 5 wire CDI box wiring diagram is an essential component of the ignition system of small engines. It is crucial to understand the wiring diagram to troubleshoot any problems that may arise. The wiring diagram consists of five wires that connect to the battery, stator, ignition coil, and kill switch. By following the wiring diagram, you can ensure that the CDI box and the ignition system operate correctly.
