Universal Motorcycle wiring system complete for honda 125 ace/cb

Honda 125's wiring system is a complex electrical network including a power source (battery or AC), starting and ignition systems, lighting, and signals, all connected via a wire loom and governed by components like a CDI unit, regulator/rectifier, fuses, and switches to manage power flow for engine ignition and vehicle functions.  

Core Components & Function

Battery/Power Source: Supplies the 12V DC power for the electrical systems. 

Ignition Switch & CDI Unit: The ignition switch initiates the current to the CDI (Capacitor Discharge Ignition) unit, which then delivers a high-voltage spark to the spark plug, igniting the fuel-air mixture in the engine. 

Regulator/Rectifier: Converts the alternator's AC power to DC and regulates the voltage to charge the battery and power the electrical components. 

Wire Loom: A bundled network of wires connecting all the electrical components, providing a structured path for electrical current. 

Fuses: Protective components that prevent damage to the electrical system by breaking the circuit in case of overloads or short circuits. 

Switches: Handle various functions, including the turn signals, headlamps, brake lights, and horn. 

Ground Wire: Provides the return path for the current, completing the electrical circuit, often represented by black wires in the system. 

How It Works

Starting: When you turn the key, a small current goes to the starter relay, which then sends a larger current to the starter motor. 

Engine Running: With the engine running, the alternator generates AC power, which is converted to DC by the regulator/rectifier to charge the battery and power the bike's systems. 

Lighting & Signals: The power from the regulated system is routed through the wire loom to switches that operate the headlamps, taillights, and turn signals. 

Engine Management: The CDI unit uses signals from the engine to time the spark plug firing, while other signals (like fuel pulse from the green wire) are sent to the gauges.
