Every engine needs a spark to ignite the fuel and make it run. The spark ignites the fuel and air mixture in the engine’s combustion chamber, creating power. In order to produce that spark, you need a 4 pin CDI ignition module. This module is responsible for converting the electrical energy into an ignition spark. In this article, we’ll look at how to wire a 4 pin CDI ignition module.
What is a 4 Pin CDI Ignition Module?
A 4 pin CDI ignition module is a type of electronic device used to provide spark to an engine. It’s usually used on small engines, such as those found in lawn mowers, ATVs, motorcycles, and other small engines. The 4 pin CDI ignition module is generally used to replace the original points-based ignition system that was installed on older vehicles.
How Does a 4 Pin CDI Ignition Module Work?
A 4 pin CDI ignition module works by converting electrical energy into a spark. This module is connected to the engine’s ignition system. When the engine is cranked, the module produces a high voltage spark that is then sent to the spark plug. This spark ignites the fuel and air mixture in the engine’s combustion chamber, creating power.
What Parts Make Up a 4 Pin CDI Ignition Module?
A 4 pin CDI ignition module consists of four main parts: a coil, a capacitor, a diode, and a transistor. The coil stores electrical energy and the capacitor stores energy that is released in bursts. The diode prevents current from flowing in the wrong direction, and the transistor acts as a switch that turns the current on and off.
What Is the Wiring Diagram for a 4 Pin CDI Ignition Module?
The wiring diagram for a 4 pin CDI ignition module is shown below. The red wire is connected to the positive terminal of the ignition coil. The black wire is connected to the negative terminal of the coil. The green wire is connected to the trigger wire from the engine’s ignition system. This wire will be used to switch the module on and off. The yellow wire is connected to the capacitor. This wire should be connected to the engine’s ground.
How to Install a 4 Pin CDI Ignition Module?
Installing a 4 pin CDI ignition module is a relatively simple process. First, you need to disconnect the battery from the engine. Then, you need to remove all the parts that are connected to the ignition coil, such as the spark plug wires and the coil itself. Once the parts have been removed, you can then install the 4 pin CDI ignition module. Connect the red wire to the positive terminal of the coil, the black wire to the negative terminal of the coil, the green wire to the trigger wire from the engine’s ignition system, and the yellow wire to the engine’s ground. Finally, you can reconnect the battery and the parts that were removed from the ignition coil.
What Are the Benefits of Installing a 4 Pin CDI Ignition Module?
Installing a 4 pin CDI ignition module has several benefits. First, it eliminates the need for a traditional points-based ignition system, which can be difficult to maintain. Additionally, it can provide a more consistent spark, resulting in better engine performance and improved fuel economy. Finally, it can reduce the chances of an engine misfire, which can cause serious damage to the engine.
Conclusion
Installing a 4 pin CDI ignition module is a great way to upgrade an engine’s ignition system. It eliminates the need for a traditional points-based ignition system, and can provide a more consistent spark, resulting in improved engine performance and fuel economy. Additionally, it can help reduce the chances of an engine misfire. Before you install a 4 pin CDI ignition module, be sure to refer to the wiring diagram to ensure everything is connected properly.
