• Ignition Coil: Transforms low-voltage electricity into high-voltage for spark plug firing.
• Stator/Alternator: Generates electricity to power the engine and charge the battery (if equipped).
• Regulator/Rectifier: Regulates voltage and converts AC to DC for charging the battery and powering accessories.
• Starter Motor: Cranks the engine for starting.
• Battery (if equipped): Stores electrical energy for starting and running accessories.
• Wiring Harness: Connects all electrical components.
• Kill Switch: Interrupts the ignition circuit to stop the engine.
• Lighting System (if equipped): Powers headlights, taillights, and other lighting components.

The wiring diagram will typically use color-coded wires and symbols to represent each component and its connections. Understanding these color codes and symbols is essential for accurate interpretation.

Practical Application
