Usually, your car doesn't make ANY sound when your alternator is bad. When the alternator goes out, the battery fails to recharge, and you can't start your car. Another symptom: your headlights go dim at night. This usually happens just before your battery dies. Another one: your turn signals flash more slowly than usual. If it goes out in daylight, it just quits firing cylinders, running rough, intermittently firing, cutting out. Then it dies, and you don't have enough power to start the engine.

Typically you know your alternator is out when you have to jump start your car numerous times. A way you can test it is by turning on your car and while it's running discount the + terminal. If the car turns off then your alternator is bad. If the car remains in then alternator is good and possible bad battery. Hope this helps
