What is the maximum crank time for GE locomotives?

• A. 20 seconds
• B. 60 seconds
• C. 45 seconds
• D. 15 seconds

Answer: (C)

Crank time is limited to protect the starter and electrical system from overheating and damage. For GE locomotives, the maximum crank time per cranking cycle is 45 seconds. This duration is long enough to try to start the engine, but short enough to prevent overheating of the starter windings and excessive current draw from the batteries. If the engine hasn’t started within that window, you should stop, wait for a cooldown period, and then attempt again. A longer duration like 60 seconds risks damaging the starter and batteries, while shorter times such as 15 or 20 seconds are usually not sufficient to achieve a reliable start under typical conditions.
