How do you tell if you have a bad alternator?
While battery issues are common culprits for electrical problems, sometimes the alternator is the real troublemaker. The alternator is responsible for charging your battery while the engine is running, so if it’s not doing its job, you could end up with a dead battery even if the battery itself is in good condition.
Signs of a failing alternator include dimming or flickering lights, especially when you are using multiple electrical components at once. You might also notice a burning rubber smell, strange noises coming from the engine area, or difficulty starting the car. One telltale sign is if your car dies shortly after a jump start this could indicate that the alternator isn’t recharging the battery as it should.

How to tell if it’s an alternator or battery?
Distinguishing between alternator and battery issues can be tricky, but there are a few ways to narrow it down. If your car starts fine but dies while running, it’s likely an alternator problem. On the other hand, if your car won’t start at all, but comes to life with a jump start, you’re probably dealing with a battery issue.
Here’s a simple test you can try. Start your car and then disconnect the positive terminal of the battery. If the car dies immediately, your alternator is not producing enough power to keep the engine running on its own. Just be careful with this test. It’s best performed by a professional to avoid any risk of electrical shock or damage to your car’s systems.
