The Causes of Car WON’T Start Clicking Noise

Every unusual car sound is a warning to a particular underlying anomaly. When car won’t start clicking noise, it could indicate issues with several components. The engine needs a thrust from the flywheel for being cranked up. The flywheel, on the other hand, depends on the starter motor. The battery is the source that supplies power for all these components. So, when the car clicks but wont start, there could be several sources of the problem.

Car Won’t Start Clicking Noise: The Probable Causes

It could either be a battery or a starter problem when the car clicks when trying to start but the engine refuses to respond. The engine cranking up involves a series of chain events. Issues with a single device or a damaged component can turn the whole system to dust. Here are some symptoms of car won’t start clicking noise and their feasible causes:

1# Rapid Clicking When Trying to Start Car

If there is a rapid-fire clicking when you turn the ignition key, low voltage or high resistance is the problem. And, the only reason for this trouble is a problematic battery. The battery issues could arise from two sources:

The Battery Is Dead – It could happen for a malfunctioning alternator or low battery charge. Check its output voltage with a voltmeter. It is definitely the source of trouble if the reading comes less than 12 V. A dead battery is not necessarily bad or damaged. If it is not transmitting power due to low electrolyte levels, recharging electrolytes will solve the problem. You should go for best car battery to avoid this such frustrating situation.

A damaged alternator could be another reason for an unresponsive battery. The car won’t start clicking noise will happen if the alternator cannot provide the requisite voltage output for any reason. Fixing or replacing it is the only solution.

If the car won’t start clicking noise but battery is good, the real culprit is the parasitic drain. Defective alternator diode or some kind of electrical problems are the main causes. You can try jumpstart the car and drive it to a garage to diagnose the problem.

Corrosion of the TerminalsClicking sound when starting car could happen when the starter motor does not get adequate power supply and the most probable reason is the corroded battery terminals. Examine the battery under the hood. If the terminals have green, blue deposits or rust buildup, you should get them cleaned to restore the voltage supply and bring the engine back to life.

Loose battery cable ends or frayed wire can cause the trouble too. Check these accessories and ensure that they are all in working order.

Starter Problems – There are various starter issues that could potentially lead to high resistance and the car won’t start clicking noise. Check for a dead starter motor, resulting from a damage or a defective triggering mechanism. Loose starter connection could be the culprit too. In that case, you have to find out the faulty wire circuit and examine it with a voltmeter. Fixing the motor will require some professional expertise but you can repair the loose connection with some skills.

You should check the motor, all the connections, and the entire circuit to find out the root of the trouble.

2# Single Click When Starting the Car

When you hear just one click at the time of turning the ignition key, it could be the faulty high current contacts inside the starter solenoid. A malfunctioning solenoid could lead to the same symptom of clicking sound when starting car by interfering with the ignition circuit.

When the contacts develop a high resistance when they are damaged or corroded. When you turn the ignition key and try to start the engine, the high resistance eats up the voltage supposed to flow to the starter, lowering its power supply and preventing it to crank up the engine.

The good thing is a new set of contacts does not cost more than $10. But, the problem is you will hardly find them in any garage or auto service center. In that case, replacing the starter assembly will be the solution.

3# Car Wont Start Just Clicks

Another probable reason for car won’t start clicking noise is a locked up or frozen engine. The locked up problem can be solved by trying to kick off the engine manually with a breaker bar and wrench. In the case of a frozen engine, switch the car on and give the engine time to warm up gradually. You can avoid this problem by refilling the coolant before the arrival of winter and not parking the car out in the open when the temperature is pretty low.

How to prevent the trouble of car won’t start clicking noise? Regular checkup and upkeep of the car battery and alternator along with a yearly inspection of the ignition system will keep the issue at check.
