Installation Procedure
Note: The gears between the ignition/start switch and the ignition lock cylinder case must be in the correct position. Failure to do so will cause a
misalignment of the gears in the ignition/start switch and the ignition lock cylinder case, which may result in a NO START or BATTERY DRAIN.
1. Use a screwdriver to rotate the ignition lock cylinder case gear clockwise to the start position - allowing it to spring return into the RUN position.
