You often hear automotive terms mentioned, but most drivers don't really know what they are. An alternator is the real power behind the things you use in your car, like your radio, climate control system, or interior lights. When it fails, your car may not start at all.

Often confused with your battery, the alternator is actually what charges your battery. As your engine runs, spinning wheels generate electricity in your alternator, which can be used for a variety of things. A high-pitched whine, a burning smell or a failure for lights to come on or the radio to work are all hints of an ailing alternator. If you suspect your alternator is failing, you can test this by jump starting your car. If it dies right after you remove the jumper cables, it is your alternator acting up rather than your battery.
