What Are the Signs of a Bad Alternator?

Your car needs the alternator to keep regenerating power as the engine runs. When the alternator breaks down, your car's electrical systems and accessories will not last much longer. That's where Rainier Automotive comes in. Read on to learn about the signs of a failing alternator.

Sign #1: Electrical/Burning Smells

The alternator is supposed to generate a lot of power. Certain issues can cause the alternator overheat. As a result, you may catch a whiff of a hot electrical smell. 

Sign #2: Odd Sounds

Your alternator has belts, pulleys, and bearings that keep it in order to generate power. If any of those parts wear out, you'll likely hear a noise.. It is often described as whining or squealing.

Sign #3: Problems with Electronic Accessories

Any accessories that draws power from your car's electrical system will run the risk of malfunctioning. When the alternator is failing, it can't supply enough power to everything at once. That may mean your radio, GPS, phone charger, power windows, or even headlights faulter. 

Sign #4: Dead Battery

Your car’s battery is needed to kickstart your engine. Without the battery starting your car, you won't be able to get anywhere. If the alternator is having issues, the battery will die off soon.

Sign #5: Electrical Warning Light

You might get a dashboard warning light that looks like a battery. While it may be misleading, it doesn't hurt to check your alternator. You shouldn't just stop after testing your battery.
