Ignition Switch: Description and Operation
CIRCUIT OPERATION
When the ignition switch is in the RUN position, it connects circuit A2 from fuse 2 in the Power Distribution Center (PDC) to circuit A22. Circuit
A22 connects to the fuse block. Through the fuse block, circuit A22 feeds circuits A20, L10, F23, C1 and F21. Circuits A20, L10, F23, and C1 are
protected by separate fuses. A circuit breaker protects circuit F21.
When the ignition switch is in the START or RUN position, it connects circuit A1 from fuse 3 in the PDC to circuit A21. Circuit A21 powers
circuits F18, F12, and F14 through the fuse block. Separate fuses protect each circuit.
In the START position, the ignition switch connects circuit A1 from fuse 3 in the PDC to circuit A41. Circuit A41 connects to either the clutch
pedal position sensor or the clutch pedal position switch bypass jumper. Also in the START position, the ignition switch connects circuit G9 to
ground.
In the ACCESSORY or RUN position, the ignition switch connects circuit A1 to circuit A31. Circuit A31 connects to the fuse block and feeds
circuits F30, L5, Xl2, and V6. Separate fuses protect each circuit.
