There are myriad problems that could prevent a car from starting. The one particular problem that grabbed our attention is the one identified with a clicking noise. You might have faced this problem when you try to turn your car on; it won’t start but is making a clicking noise. This problem is mostly caused because of issues with the battery or the connections linking to the battery. Here we have mentioned the root causes that might be causing the problem.
The first problem that you need to check is if the battery is drained. Did you leave the headlights or an interior light on while sleeping, or did you do anything else that drained the battery? If that’s the case, a set of jumper cables and another car with a solid battery should get you back on the road quickly.
Another possibility is that the alternator, which creates the power that recharges the battery, isn’t working properly. The starter motor drains a lot of the battery’s stored energy, and the alternator is designed to refill it, so if your battery can take a charge and tests well, it has to be rejuvenated between starts. A technician should test an alternator to see if it’s in good operating order.
Connections with the battery
Inspect the clamps that hold the cords to the battery. They may have become loose due to road vibrations and are no longer making proper electrical contact, requiring tightening. Disconnecting the wires and clearing off the muck may reestablish excellent connections if the corrosion has built upon the terminals.
The battery may or may not be able to maintain a charge. Depending on where you live and how you drive, batteries can last anywhere from three to six years. Most parts retailers will test a battery for free in order to determine whether or not you require one.
If the battery appears to be charged (the headlights, stereo, and other devices all work), but you only hear one click, the starter motor or solenoid is most likely to blame. The solenoid is the switch that turns the flywheel and starts the engine by engaging the starter motor. This is something a technician should diagnose unless you’re a skilled do-it-yourselfer on auto repairs.
Also check why is your car overheating vibrating when idle.
