As the main components in the starter begin to wear out, you will notice that your car cranks slowly or weakly when you turn the key. This occurs when the equipment struggles to turn the flywheel at the proper speed. If this continues to occur, your engine will eventually fail to activate altogether. Alternator problems often present themselves with a faint clicking sound as you attempt to start your vehicle and eventually the alternator will stop charging the battery. At that point, your car will fail to respond when you turn the keys in the ignition. Since both of these problems start with subtle symptoms, it’s smart to have your technician diagnose and repair the worn components as early as possible.
