Hello Kammi10,
Go out to your car and with it running, use a multimeter set to Volts Direct Current (VDC). Measure the voltage at the battery, it should be somewhere around 14.5 volts if the alternator is working properly. If you can, have someone run the engine up to about 2000 RPM's and hold it for about 20 seconds while you measure the voltage at the battery again. You should see a increase in voltage to the battery. If this test is good, you might have a bad voltmeter. Try tapping on it and see if it goes up any.
