What are the symptoms of a faulty car starter?

[McHaven]

Here are the symptoms that occur when a car starter is faulty: 1. After turning on the ignition switch, the starter spins without engaging. 2. After turning on the ignition switch, the electrical system is normal but the starter does not turn. 3. When turning the ignition switch to the start position, you may hear a grinding noise caused by the starter drive gear impacting the flywheel teeth. 4. After turning on the ignition switch, the starter does not rotate, and the electromagnetic switch makes a clicking sound. Here are the extended reasons for starter failure: 1. The armature shaft inside the starter is bent or the bearings are too tight, the commutator is dirty or burned, the brushes are excessively worn, the springs are too weak to make contact, or the armature coil or field coil is short-circuited, open-circuited, or grounded. 2. The starter solenoid switch coil is open-circuited or the contact disc has poor contact.
