Q: How to check Neutral Safety Switch on Ford Thunderbird?
A: Engine can be started in every gear. The engine should only run if the clutch pedal has been stepped on (for manual cars) or when the car is in either Park or Neutral (for automatic vehicles). Ensure that the steering column lock will allow the key to turn to "Lock" position only when the shift lever is in Park. The key must not be released unless it is turned to Lock.
