CAUTION
Before performing any tests with a continuity light or
ohmmeter, disconnect the component from the wire
harness. This ensures you are testing the component
rather than another circuit.
Ignition Switch
Purpose
The ignition switch provides the proper switching for the
starter, ignition, accessories, and safety circuits.
Location
The ignition switch is located on the control panel (Fig.
223).
How It Works
Detents inside the switch gives it 3 positions: OFF,
RUN, and START. The START position is spring loaded
so the cylinder automatically returns to RUN once the
key is released (Fig. 224).
