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.

Verify the alignment of the gear (1) in the ignition and start switch (2). If the gear (1) is not in the position shown then turn the gear in the ignition and start switch (2) until you reach the correct position.
