Understanding the Predator 420cc Ignition Switch Wiring Diagram

A typical Predator 420cc ignition switch wiring diagram illustrates the connections between the switch, the engine’s electrical system, and safety components. Key wires to understand include:

• Battery Wire (B/BAT): Connects directly to the positive terminal of the battery, providing power to the ignition system.
• Ignition Wire (IG): Supplies power to the ignition coil when the switch is in the “ON” position.
• Start Wire (ST): Activates the starter motor when the switch is turned to the “START” position.
• Ground Wire (G/GND): Provides a return path for the electrical current, essential for completing the circuit.
• Kill Switch Wire (KS): Used to ground the ignition coil, effectively shutting off the engine; often linked to a low oil sensor.

Note: Wire colors may vary. Always refer to the specific wiring diagram for your Predator 420cc engine model. Correctly identifying each wire is crucial when troubleshooting or rewiring the ignition system.
