Why is my starter clicking but no turn?
If your car's starter is clicking but not turning over the engine, it could be due to a few common issues. The most likely causes are a dead or dying battery, a faulty starter motor, or a problem with the starter solenoid or wiring. Let's explore these potential problems in more detail.
Checking the Battery
The first thing to check is the condition of your car's battery. If the battery is old, discharged, or damaged, it may not be able to provide enough power to the starter motor to crank the engine. You can test the battery's voltage with a multimeter - a healthy battery should read around 12.6 volts with the engine off. If the voltage is low, try jump-starting the car or replacing the battery.
Inspecting the Starter Motor
The starter motor is responsible for turning the engine over when you turn the key. If the starter motor is faulty, it may click when you try to start the car but not actually engage the flywheel to crank the engine. You can have a mechanic test the starter motor to see if it needs to be replaced.
Checking the Starter Solenoid
The starter solenoid is an electromagnetic switch that connects the battery to the starter motor when you turn the key. If the solenoid is malfunctioning, it may cause the clicking sound without actually engaging the starter. You can try tapping the solenoid lightly with a tool to see if that gets the starter to turn over, but a faulty solenoid will likely need to be replaced.
Inspecting the Wiring
Finally, the issue could be with the wiring between the battery, starter, and solenoid. Loose, corroded, or damaged wiring can prevent the starter from receiving the necessary power to crank the engine. Have a mechanic inspect the starter wiring and connections to ensure they are in good condition.
If you've checked the battery, starter, solenoid, and wiring, and the clicking persists, it's best to have a professional mechanic diagnose and repair the issue to get your car back on the road.
Why is my car making a clicking noise but not turning on?
A rapid clicking noise when starting your car typically indicates an electrical problem, often due to a dead or dying battery. A single click may point to a faulty starter or starter relay, requiring professional inspection if a jumpstart doesn't work.
Why is my starter clicking but not turning over?
A starter that clicks but doesn't turn over is most commonly caused by a weak or dead battery, or poor connections at the battery terminals. Other potential causes include a faulty starter motor or solenoid, a bad alternator, or wiring issues.
Common causes

- Weak or dead battery: This is the most frequent cause. The battery has enough power to engage the starter's solenoid (the click), but not enough to turn the engine.
- Loose or corroded battery terminals: A bad connection prevents the starter from receiving the necessary current, even if the battery is fully charged.
- Faulty starter motor: The starter itself may have failed, or the internal bushings might be worn, causing it to bind up.
- Faulty starter relay or solenoid: The relay may be working but not sending enough power to the starter motor, or it could be completely faulty.
- Bad alternator: If the alternator isn't charging the battery correctly, the battery will eventually drain, leading to a no-start situation.
- Wiring problems: Loose, corroded, or damaged wires in the starter or alternator circuit can interrupt the flow of electricity.
Troubleshooting steps
- Check the battery terminals: Make sure the connections are clean and tight. Clean off any corrosion, as this can be an easy and effective fix.
- Try to jump-start the car: If the car starts after a jump-start, your battery was likely the issue. If it still only clicks, the problem is likely elsewhere.
- Test the battery: A professional can test the battery to see if it's holding a charge. A multimeter can also provide a voltage reading—a healthy battery should be over 12.612.612.6 volts when the engine is off.
- Inspect the starter: If the battery is good, the problem may be with the starter motor or solenoid itself.
- Check the alternator: A faulty alternator can cause the battery to die. Have the alternator tested to ensure it's charging properly.
- Listen to the click: A rapid, repetitive clicking often points to a weak battery, while a single, loud click may point to a bad starter motor or solenoid.
Should I try tapping the starter with a hammer?
Hitting the starter with a hammer is a valid trick on old cars with old starters, but many new replacement starters come with a warning that says DO NOT HIT WITH HAMMER, as the magnets are held in only with adhesive, and can be dislodged if you smack them.
How to tell the difference between a bad solenoid and a bad starter?
If the starter is bad and the solenoid works, you should hear a clunk from the solenoid, then silence from the starter. If the solenoid is bad, nothing happens. First check for good connections, including grounding of the battery.
