What is one potential cause of starter motor failure?

Starter motor failure can result from various factors, and one comprehensive answer to this question is that all the identified issues can contribute to the problem.

High resistance in battery cables can impede the flow of electrical current to the starter motor. When there's increased resistance, the motor may not receive sufficient voltage to operate correctly, leading to failure. This condition can typically be caused by frayed or damaged cables that limit the effective current supplied.

Low cranking speed is another potential cause of starter motor failure. If the motor isn't able to turn over the engine at the required speed, it may indicate that either the starter itself is failing or that it is not receiving enough power due to other issues like inadequate voltage from the battery or the aforementioned high resistance in the cables.

Corrosion on terminals can also have a detrimental effect. If the connections at the battery or starter are corroded, it can create resistance and reduce the current flowing to the starter motor. This poor connectivity can prevent the starter from engaging or cause intermittent failures.

Each of these factors can independently lead to starter motor failure, and when combined, they certainly increase the likelihood of a no-start situation. Therefore, understanding that all these conditions can contribute provides a more comprehensive viewpoint on diagnosing and addressing potential starter motor
