Question

What is the function of a neutral safety switch in the cranking circuit?

a) to prevent accidental engine startup in neutral gear
b) to prevent engine startup when an automatic transmission is in gear
c) to prevent the engine from being over-revved in neutral
d) to prevent the starter motor from overspeeding after engine start

Answer 1

The neutral safety switch in a cranking circuit is there to prevent engine startup when an automatic transmission is not in Park or Neutral. This prevents unintended vehicle movement and enhances safety by ensuring the vehicle is stationary during startup.

Step-by-step explanation:

The function of a neutral safety switch in a cranking circuit is b) to prevent engine startup when an automatic transmission is in gear. This critical safety device ensures that a vehicle with an automatic transmission will not start if the transmission is not in "Park" or "Neutral" position.

The neutral safety switch blocks the electric current to the starter unless the transmission is in a safe starting gear. Without this feature, starting the engine while in gear could lead to unintended vehicle movement and potentially cause an accident. Therefore, it promotes safety by ensuring a stationary startup.
