There is nothing more frustrating than a dead car. When your car won’t start, it is likely a problem with the battery, alternator or starter. But how do you know which part is causing your issue?

If you are experiencing any of these issues, your battery likely is at fault. Replacing the battery is something you can do yourself or you can have your trusted mechanic help out. If the battery checks out, it’s time to look at the alternator.
A key part of your vehicle’s charging system, the alternator charges the battery when the engine is running and also powers the electrical system. An alternator typically lasts for 8-12 years, so it isn’t something that has to be replaced as often as other parts like the battery. If your alternator fails, your battery will lose its charge since the alternator won’t be able to keep it charged up. A dead battery is your initial sign that something could be wrong with the alternator. Here are some other symptoms of a bad alternator.
