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.
To ensure these components are kept in perfect shape, be sure to schedule regular car maintenance. This will help avoid parts from wearing out and damaging your vehicle. A starter rebuild or alternator rebuild is also a possibility.
Your technician will hook up a diagnostic device to the starter, alternator and battery to determine which of the components are causing your vehicle’s symptoms. Your tech will compare the readout on the display to the manufacturer’s service limits to determine the faulty part. Once your technician finds the cause of the problem, the proper starter or alternator repair services can be completed.
When performing alternator repairs, the technician must simply pull the damaged or defective part out of the vehicle and replace it with a new one. Most commonly, technicians perform the starter and alternator replacement by removing the old hardware and parts using a socket set and other hand tools. The replacement parts quickly bolt into the engine bay in the exact same position as the old components.
