IMPORTANT: 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/start switch (2). If the gear (1) is not in the position shown then turn the gear in the ignition/start switch (2) until you reach the correct position.
