What Is A Starter？

A starter initiates the engine's operation. When you turn the ignition key or press the start button, the starter motor is activated, drawing electrical power from the battery. It then engages with the engine's flywheel or flexplate, turning the engine over and starting the combustion process. Without a functioning starter, the engine cannot begin running.

What Causes Starter Failing?

Dirty or Corroded Connections:

Built-up dirt or corrosion at the starter connections can cause higher resistance between circuits, disrupting the flow of power. This can lead to a very weak crank or complete failure to crank. Regular maintenance and cleaning of these connections can help prevent this issue.

Battery Problems:

A corroded or weak battery can lead to starter failure. Corrosion can occur due to overheating, leaking, or simply the battery's age. If the battery cannot provide enough power to the starter, the engine may not crank.

Damaged or Worn-Out Parts:

Over time, parts within the starter system, such as the starter motor, cables, and relay, can wear out. These components are crucial for conducting and distributing electrical power. When they fail, the starter may not function correctly.

Oil Leaks:

Older vehicles are particularly susceptible to oil leaks, which can be caused by engine wear and tear. If engine oil leaks onto the starter, it can cause the starter to become inoperable. This not only necessitates repairing the oil leak but also replacing the affected starter.

Bad Relay:

A faulty starter relay can result in either an engine that won’t turn over or a starter that continues to crank even after the engine has started. This can cause significant issues and requires immediate attention to replace the bad relay and ensure proper starter operation.

Loose Wiring:

Loose wiring to and from the starter can disrupt its connection to electrical power, causing the engine to fail to crank. Ensuring that all wiring is securely connected and in good condition can prevent this issue. Regular inspections can help identify and fix any loose connections before they lead to starter failure.

What To Do If The Starter Motor Fails?

If your starter motor fails, the first step is to perform a thorough inspection to determine the cause of the failure. Check the battery connections to ensure they are secure and free of corrosion, as poor electrical connections can often mimic starter motor issues. Additionally, test the battery itself to confirm it has sufficient charge. If the battery is functional, inspect the starter motor for signs of wear, such as damaged gears or faulty electrical components.
