If you’re experiencing car troubles or performance issues you believe are related to the alternator, you can diagnose whether or not the alternator is to blame with a few inexpensive tools. You will need a volt meter and a test light. Hook up the meter to the battery terminals and make sure the battery itself has enough voltage. If the battery is good, connect the meter to the alternator and start the engine. If the meter is reading less than 13 volts, your alternator is not performing correctly and will need to be replaced.
