Two-Wire CDI to Coil Motor:
1. Power Supply Wire: This wire provides power to the CDI box from the battery or another suitable power source. It is usually marked with a "+" or "B+" and is typically red or orange.
2. Trigger Wire: This wire carries the trigger signal from the engine's ignition system to the CDI box. It is usually marked with a "+" or "Trig" and can be varying colors based on the engine. When this wire receives a pulse, it triggers the CDI box to discharge the high-voltage energy stored in its capacitor.
Three-Wire CDI to Coil Motor:
In some setups, there may be an additional wire for grounding purposes. This wire usually has a "-" or "GND" marking, is black or brown in color, and should be connected to a suitable ground point on the engine or chassis.
The CDI box uses the trigger signal received from the trigger wire to control the timing of the electrical discharge through the coil wire, thus initiating the ignition process in the engine.
Please note that the specific wiring colors and terminal markings may vary depending on the model and manufacturer of the CDI box and coil motor used in your application. Always refer to the documentation or wiring diagram provided with your engine or components for accurate and reliable wiring instructions.
