5 Warnings Your Alternator Is Going Bad

Your vehicle relies on the alternator for power. This part generates voltage and powers your battery and electrical components. If the alternator is failing, you’ll notice some unusual things happening. If it dies completely, you won’t be able to start your car, truck, or SUV. Here are five warning signs that the alternative is in trouble, so you can have the part replaced before it becomes a huge hassle.

Noticeable Light Changes

Your automobile’s headlights, taillights, and interior lights will dim as your alternator struggles to produce power. You may also notice power loss in your power accessories, such as the windows or seat adjustments. In severe cases, your radio and other console systems can turn off unexpectedly.

One Light That Turns On…

If the alternator is dying, your other lights will dim but a dashboard warning light will turn on. If you have it, you will either see the alternator warning light, “ALT,” or the generator warning light, “GEN.” If you don’t have either of these dashboard warning lights, your battery warning light will illuminate.

Battery Problems

To get your vehicle started, the alternator powers the battery which, in turn, powers the starter. If your vehicle has trouble starting or fails to start at all, it could be that the alternator isn’t powering the battery. The issue could also be the battery itself, as the standard battery life is only three years. 

Strange Odors

How the alternator generates power is through a system of belts. If the belts are not moving as they should, you might smell burning rubber underneath your hood. This could be the alternator belt or another system belt. You may also smell hot electricity if a belt has slipped and cannot produce normal energy output.

Audible Clues

Finally, your alternator has a motor inside of it that is made up of many moving parts. As the parts wear down, which they can do over time, you might grinding or whining. Usually, it’s the bearings or bushings that make these noises. Either way, the alternator needs to replaced if you hear strange noises coming from it.
