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 continuity exists between the terminals listed
for the START and RUN switch positions. Verify that
there is continuity between the terminals G and M in
the OFF switch position only (Fig. 0860).
