  If the MTU Engine doesn't turn when you actuate the starter, there are several potential causes. It could be due to a low or defective battery, in which case you should charge or replace it. Defective cable connections can also be the reason, so check if they are properly secured. Issues with the engine wiring or starter itself could be the problem, so check the cable connections. Also, make sure that the assemblies or connectors are seated correctly by performing a visual inspection, and check for loose plug-in connections. If the running gear is blocked, preventing manual barring of the engine, it is recommended to contact Service.
