If your MTU Engine doesn't turn when starting, it could be due to several reasons: * A low or faulty battery. In this case you should charge or replace the battery. * Faulty cable connections. Check the cable connections to ensure they are properly and securely seated. * For electric starters, the engine cabling or starter itself may be faulty. Check whether cable connections are properly secured. * For compressed air starters, the cabling on the starting valve or the starter could be defective. Check whether cable connections are properly secured. * Loose assemblies or connectors in the engine/generator control: Perform a visual inspection to check for loose connections. * Loose plug-in connections in the engine governor: Check these connections to ensure they are secure.
