If you are looking to install a new CDI in your Chinese motorcycle, it is important to have a wiring diagram handy. The wiring diagram will help you to understand the different connections that need to be made and ensure that the installation is done correctly. In this article, we will provide you with a detailed wiring diagram for a Chinese 5-pin CDI.
What is a CDI?
A CDI or Capacitor Discharge Ignition is an electronic ignition system that is used in motorcycles, scooters, ATVs, and other small engines. The CDI system consists of a capacitor, a charging circuit, a trigger circuit, and an ignition coil. The CDI system stores electrical energy in the capacitor, which is then discharged into the ignition coil to create a spark. The CDI system can provide a reliable ignition system even at low speeds and low engine temperatures.
Wiring diagram for Chinese 5-pin CDI
Here is the wiring diagram for a Chinese 5-pin CDI:
| Color | Function | Pin |
|---|---|---|
| Black | Ground | 1 |
| Red | Battery Positive | 2 |
| Green | Trigger | 3 |
| Yellow | Ignition Coil Positive | 4 |
| White | Lights/Accessories Power | 5 |
The wiring diagram shows the different pins of the CDI and the function of each pin. The black wire is connected to ground, the red wire is connected to the battery positive terminal, the green wire is connected to the trigger signal from the stator, the yellow wire is connected to the positive terminal of the ignition coil, and the white wire is connected to power the lights and accessories.
FAQ
What is the function of the trigger wire?
The trigger wire is used to send a signal from the stator to the CDI to tell it when to fire the spark plug. The signal is generated by the stator as the engine rotates and is sent to the CDI at a specific time based on the timing of the engine.
What is the function of the ignition coil?
The ignition coil is used to convert the low voltage, high current signal from the CDI into a high voltage, low current signal that can be used to create a spark at the spark plug. The ignition coil is an electromagnetic device that consists of a primary winding and a secondary winding. The primary winding is connected to the CDI and the secondary winding is connected to the spark plug.
What is the function of the white wire?
The white wire is used to power the lights and accessories on the motorcycle. This wire is typically connected to the regulator/rectifier, which converts the AC voltage from the stator into DC voltage that can be used to power the lights and accessories.
What do I do if my CDI is not working?
If your CDI is not working, you should check the wiring connections to make sure they are correct and secure. You should also check the trigger signal from the stator to make sure it is within the specified range. If the wiring and trigger signal are both correct, you may need to replace the CDI.
What is the difference between a 5-pin and a 6-pin CDI?
The main difference between a 5-pin and a 6-pin CDI is the number of connections. A 5-pin CDI has five connections, while a 6-pin CDI has six connections. The extra pin on a 6-pin CDI is typically used for a kill switch or a rev limiter.
In conclusion, the Chinese 5-pin CDI wiring diagram is an important tool for anyone who is installing a new CDI in their Chinese motorcycle. The wiring diagram provides a clear and concise guide for connecting the different pins of the CDI to the correct wires on the motorcycle. Make sure to follow the wiring diagram carefully to ensure that your CDI is installed correctly and functions properly.
