Question 1 of 27070

If an auxiliary diesel engine equipped with an electric starting system cranks very slowly after repeated attempts to start, the cause could be a/an __________.

🔍 Key Concepts

• Battery condition and voltage drop under load for electric start systems • How mechanical faults (like broken teeth) usually show up as noise or failure to engage, not slow continuous cranking • The effect of compression pressure and engine load on starter speed

💭 Think About

• When a starter motor cranks slowly but still turns the engine, what does that tell you about the electrical supply versus the mechanical engagement? • Which option would most likely cause gradual slowing of the crank speed over repeated attempts, rather than a sudden grinding noise or complete failure to crank? • Think about which condition would make it harder for the starter motor to spin the engine, and whether that would show up as slow cranking, no cranking, or normal cranking but no firing.

✅ Before You Answer

• Ask yourself which choice is most directly related to starter load and speed rather than combustion or lubrication once running • Eliminate any options that would more likely cause no engagement or engine damage while running, instead of just slow cranking before start • Consider which fault would become worse after repeated cranking attempts because of electrical or mechanical heating or stress
