  If the MTU Engine doesn't turn when the starter is activated, it might be due to a low or faulty battery. In this case, charge or replace the battery. Also, check if cable connections are properly secured. The engine cabling or starter could also be faulty, so inspect the cable connections. If the problem persists, contact Service. Faulty assemblies or connectors can also cause this issue, so perform a visual inspection. Finally, check if the running gear is blocked, preventing the engine from being barred manually. If so, check plug connections and contact Service.
