It is your car alternator, that has the job, to generate electricity to recharge the battery.
Because, a car battery, does not have the power; to start and run a car on its own for very long.
So, without a properly functioning alternator, a new car battery, might only last about 20 to 30 minutes.
As a result, the car alternator recharges the battery; while the engine is running, ensuring that your battery is good.
Keeping Accessories Powered
Nearly every part of the electrical system, is mostly powered by the car alternator. Although, some electricity may be taken directly from the battery.
Electrical system components include:
- Engine cooling fans.
- Fuel injection system.
- Ignition coils.
- Power steering.
- Power windows.
- Windshield wipers.
So, if you suspect that your car alternator is not working properly, turn off all your accessories. It will help you get where you are going, until your alternator can be fixed.
One of the most common problems, people have with their cars pertains to their car alternator. These devices have a life of about 5 years, at the most before you need to replace it. You will know when your alternator starts to go bad. Because, the lights of your car will start dimming. There may even be a growling sound or strange smell; that comes from underneath the hood of the car.
And of course, the worst case scenario is if this happens, while you are driving. Because, it will cause your car to stall altogether. Next, your engine will not turn over at all. Then you will be forced to, pull over to the side of the road and call someone for roadside assistance.
Diagnosing Car Alternator Problems
