🔍 Key Concepts

• Difference between an engine that "will not crank" and one that "will not turn" • What it means that an engine can be "barred over" by hand • Common electrical vs. mechanical reasons a diesel won’t crank

💭 Think About

• First, think about what system is responsible for CRANKING the engine versus what allows the crankshaft to physically turn • If you can bar the engine over by hand, what does that tell you about water in the cylinders or a seized driven component? • Which of the choices would prevent the starter from doing its job, even though the engine itself is free to turn?

✅ Before You Answer

• Confirm that barred over means you can manually rotate the crankshaft with a bar on the flywheel or turning gear • Ask yourself whether water in the cylinder or a seized driven component would still allow manual rotation • Focus on which option affects the starting circuit and not the engine’s internal ability to turn
