If you’re looking for a reliable 4 pin CDI box wiring diagram, then you’ve come to the right place. A CDI (Capacitor Discharge Ignition) box is an essential part of any motorcycle, ATV, or dirt bike. It’s responsible for delivering a spark to the engine’s ignition system, which is vital for starting and running the engine.In this article, we’ll be discussing everything you need to know about a 4 pin CDI box wiring diagram. We’ll provide you with a step-by-step guide on how to wire a CDI box, explain its components, and answer some frequently asked questions.
Understanding the CDI Box Components
Before you start wiring your CDI box, it’s essential to understand its components. A typical CDI box consists of the following:- Stator: It’s responsible for generating the electrical energy required to charge the CDI box capacitor.- Pickup coil: It senses the magnetic field generated by the flywheel, which triggers the CDI box to send a spark to the ignition coil.- CDI box capacitor: It stores the electrical energy generated by the stator and releases it in the form of a high-voltage spark.- Ignition coil: It amplifies the voltage provided by the CDI box capacitor and sends it to the spark plug to ignite the fuel-air mixture.
Wiring the CDI Box
Wiring a CDI box may seem daunting, but it’s not as complex as it seems. The following is a step-by-step guide on how to wire a 4 pin CDI box:
Step 1: Disconnect the battery to ensure your safety while working with electrical components.
Step 2: Locate the stator and the pickup coil wires. The stator wires are usually three in number, while the pickup coil wires are two.
Step 3: Connect the stator wires to the CDI box in the following order: black/white (ground), yellow (AC voltage out), and white (AC voltage out).
Step 4: Connect the pickup coil wires to the CDI box in the following order: green (signal) and black (ground).
Step 5: Connect the ignition coil wires to the CDI box in the following order: black/white (ground) and blue (positive).
Step 6: Finally, connect the CDI box capacitor wires to the CDI box in the following order: red (positive) and black (ground).
