Drive to your local auto parts store and have the electrical system checked. You can also check the output of the alternator at the battery with the engine running. You should read 13.5 to 15.5 volts with a digital DC volt meter. If it is less or more than these figures it is defective.

How do you know when alternator is bad?

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
