ENGINE IGNITION CIRCUIT
The engine ignition circuit is independent of all other circuits except the kill circuit. It consists of the ignition coil
with internal igniter, spark plug, RPM limiter, and connecting wires (Figure 11-6, Page 11-9).
ENGINE KILL CIRCUIT
The ignition coil supplies electrical power to the spark plug; therefore, the proper way to stop the engine is to
run this electrical power to ground, bypassing the spark plug (Figure 11-7, Page 11-10).
The engine kill circuit consists of the key switch and connecting wires. The engine can be stopped by turning
the key switch to the OFF position. See Lockout Cam Circuit on page 11-11.
