A maximum of how many consecutive cranking periods are allowed?

• A. 2
• B. 4
• C. 3
• D. 5

Answer: (C)

When starting the rotor system, the starter and electrical system can overheat or wear quickly if you crank too many times in a row. The procedure sets a limit to protect these components, allowing only three consecutive cranking periods. After the third attempt, you should stop, let things cool, and follow the checklist to troubleshoot or relaunch as appropriate before attempting again. Exceeding this limit risks damaging the starter or draining the battery, which is why options that permit more than three cranking periods aren’t allowed. Two cranks would be within some limits, but the specified maximum is three, so the best practice is to stop after the third and reassess.
