What are the symptoms of a faulty car starter?
2 Answers
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.
I remember one time when my car's starter failed, it was truly frustrating. When turning the key, the engine didn't make a sound at all—completely silent. Occasionally, I could hear a metallic clicking noise. If the engine barely turns over but does so very slowly, the starter might be severely worn. That time, I had to tow it straight to the repair shop. It's important to pay attention to these details while driving, such as any unusual noises during cold starts. Starter components can wear out and suddenly fail, so I recommend not waiting until it breaks down to check. During maintenance, have the technician test the electrical circuits and replace parts in time to avoid the embarrassment of being stranded on the road.
