If you are looking to understand the 110cc 5 pin CDI wiring diagram or even trying to set one up, then you have come to the right place. CDI stands for Capacitor Discharge Ignition, which is a system used in small engines to provide a high voltage spark to the spark plug.
This article will guide you through the wiring diagram, explain the different components, and provide FAQs to help you get started.
What is a CDI and How Does it Work?
A CDI unit is an electronic device that stores an electrical charge and then discharges it through an ignition coil to produce a high voltage spark. It works by converting the low voltage DC from the battery into a high voltage AC that is needed to power the ignition coil.
When the stator coil generates electricity, it charges the capacitor in the CDI unit. The trigger coil senses the position of the engine’s crankshaft and tells the CDI unit when to release the stored energy in the capacitor. This energy is then sent to the ignition coil and produces a spark at the spark plug.
Components of a CDI wiring diagram
A CDI wiring diagram consists of several components, including:
| Component | Description |
|---|---|
| CDI unit | The electronic device that stores and discharges electrical charge. |
| Stator coil | Generates electricity to charge the capacitor in the CDI unit. |
| Trigger coil | Detects the position of the crankshaft and sends a signal to the CDI unit to release the stored energy in the capacitor. |
| Ignition coil | Receives the energy from the CDI unit and produces a high voltage spark at the spark plug. |
| Spark plug | Produces a spark that ignites the air-fuel mixture in the combustion chamber. |
Each component is connected to the other by wires and the CDI wiring diagram shows how each wire should be connected to ensure proper functioning of the system.
CDI Wiring Diagram for 110cc Engines
Here is a detailed wiring diagram for a 110cc 5 pin CDI:
The diagram shows how the CDI unit, stator coil, trigger coil, ignition coil, and spark plug are connected.
The wiring diagram is color-coded to make it easy to understand. The wires that are connected to the CDI unit are marked in red, the wires that are connected to the stator coil are marked in green, and the wires that are connected to the trigger coil are marked in blue.
It is important to follow the wiring diagram carefully when setting up the CDI system to ensure that it works properly.
FAQs
Q. What is the purpose of a CDI?
A. The purpose of a CDI is to provide a high voltage spark to the spark plug, which ignites the air-fuel mixture in the combustion chamber of a small engine.
Q. How do I know if my CDI is bad?
A. If your engine is not starting or has a weak spark, then the CDI may be bad. You can test the CDI using a multimeter to check its resistance and continuity.
Q. Can I use a CDI from a different engine?
A. No, it is not recommended to use a CDI from a different engine as it may not be compatible and could cause damage to your engine.
Q. What is the difference between a 4 pin and 5 pin CDI?
A. The main difference between a 4 pin and 5 pin CDI is the number of pins that are used to connect the CDI unit. A 5 pin CDI has an extra pin for the kill switch, which allows you to turn off the engine using the kill switch. A 4 pin CDI does not have this feature.
Q. How do I connect the CDI wiring?
A. You should follow the wiring diagram carefully to ensure that the CDI wiring is connected properly. Each wire should be connected to the correct component and should have a tight connection to ensure that it works properly.
Q. Can I install a CDI myself?
A. Yes, you can install a CDI yourself if you have some basic knowledge of electrical systems and some tools. However, if you are not comfortable with electrical systems, it is recommended to seek the help of a professional.
With this information, you should now be able to understand the CDI wiring diagram and even install one yourself. Remember to follow the wiring diagram carefully and seek professional help if needed.
