1. The green wire is the ground wire, just the ground wire in the wiring harness (also green).
2. The blue (usually blue/white or blue/yellow) is the trigger coil wire, which is connected to the igniter.
3. Yellow and white are lighting charging coil wires, which are connected to the same color wires of the rectifier.
4. Red (usually black/red or white/red) is the magneto ignition coil wire, which is connected to the igniter to provide ignition power to the igniter.
The two green and ** are not connected, it is for changing the DC, it has no effect.
Detailed Information
Motorcycle Electrical Wiring:
The electrical wiring of motorcycles is basically similar to that of cars. Electrical circuits are divided into power, ignition, lighting, instrumentation and audio parts.
The power supply part is generallycomposed of an alternator (or powered by a magneto charging coil), a rectifier and a battery. Motorcycle magnetos also have various structures depending on the motorcycle model. Generally, there are two forms: flywheel magneto and magnetic rotor magneto.
Flywheel magnetos are generally used on small displacement micro and light motorcycles. Inside the flywheel, four magnets are evenly distributed, rotating with the engine crankshaft, and the stator frame is fixed on the crankshaft. , magneto coils, lighting coils and circuit breaker assemblies are attached to it. As the flywheel turns, magnetic field lines pass through each coil alternately, causing the coils to generate an induced alternating current.
In the magnetic rotor type magneto, its structure is opposite to the above. Six magnets are evenly distributed around the circumference of the rotor. The magnets and rotor are die-cast with aluminum alloy. The rotor is keyed to the crankshaft. There are six sets of coils wound around an iron core distributed throughout the stator. As the rotor rotates in the stator, magnetic field lines alternately pass through the stator coil, causing it to induce an alternating current.
There are three types of ignition methods for motorcycles: battery ignition system, magneto ignition system and transistor ignition system. In the ignition system, there are two types: contact capacitor discharge ignition and non-contact capacitor discharge ignition. The English abbreviation for non-contact capacitive discharge is C.D.I. C.D.I refers to a combined circuit consisting of a capacitor charge and discharge circuit and a thyristor switching circuit, commonly known as electronic ignition.
There are sons ofdifferent colors distributed throughout the motorcycle circuit. It is customary to use the red wire as the "+" power wire, the black wire as the "-" wire, the orange wire as the wire leading to the ignition coil and the magnetic wire. The motor output current is the white wire, the blue wire is the headlight wire, etc. This is just general usage for reference.
