      Cole KerrAug 17, 2025
      If the MTU Engine doesn't turn when the starter is activated, there are several potential causes: * A low or faulty battery. In this case, charge or replace the battery. * Faulty cable connections. Ensure that all cable connections are properly secured. * Faulty engine cabling or starter. Check the cable connections and contact service. * Faulty Assemblies or loose connectors. Check connectors. * Loose plug-in connections. Check plug connections and contact service. * Blocked running gear. This prevents the engine from being barred manually.
