Alternating ignition with dual wires. Jump-start method: To start a motorcycle without a key, connect the red and black wires together. Locate the ignition wires - one red (positive) and one black (negative). Touch the two wire ends together to start the motorcycle. Ignition system: Consists of components like the ignition coil, CDI unit, high-voltage coil, and spark plug. The primary current from the motorcycle's ignition coil enters the ignition unit, then flows through the high-voltage coil where it's amplified. This high-intensity current reaches the spark plug to ignite the fuel-air mixture in the cylinder. The resulting high-pressure combustion drives the crankshaft to perform work.
