What Causes the Abnormal Noise During Ignition After Replacing the Starter?

[DelVivian]

The abnormal noise during ignition after replacing the starter may be caused by issues with the starter's control circuit, problems with the starter brushes, insufficient battery voltage, or a malfunctioning relay. Starter Operation: The starter utilizes three components to achieve the entire starting process. The DC series-wound motor draws current from the battery and generates mechanical motion in the starter's drive gear. The transmission mechanism engages the drive gear with the flywheel ring gear and automatically disengages after the engine starts. The circuit of the starter is controlled by an electromagnetic switch. Common Issues with Slow Starter Rotation: If the battery is dead or has weak power, the starter may fail to rotate or rotate slowly. Loose or detached starter wiring, or a malfunctioning switch or solenoid switch, can also cause this issue. Worn brushes, misaligned brush surfaces, weak springs, or poor contact with the commutator may lead to poor performance. Additionally, short circuits or open circuits in the field coils or armature coils can result in slow starter rotation.
