How It Works

Detents inside the ignition switch give 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.

Testing

1. Disconnect the switch from the wiring harness.
2. Verify that continuity exists between the terminals
listed for the START and RUN switch positions.
Verify that there is NO continuity between the
terminals in the OFF switch position (Fig. 1209).
