2. Battery Without Power/Charge

We can describe this situation as a dead battery. As its name suggests, a battery goes to its ending point. The inability of a battery makes everything useless, such as headlights, ignition, and other accessories.

Battery without the ability to empower the car is a good symptom of alternator failure. However, a battery can die for other reasons, such as age.

If everything is fine, but the battery isn’t working correctly, you should check the alternator. And change it with a new one if it’s damaged.

Failing or slowing down car accessories typically happens for insufficient power supply from the alternator. It can result in slowing the window closing or ‘off’ signs of the seat warmer without any reason.

The same thing may happen with the speedometer and other devices. All these signs indicate a faulty alternator, so change it right away.

Stalling and difficulty starting the engine is other clear symptom of alternator failure. As we know, a defective alternator can’t help charge your car battery.

If you get burning smells like rubber or wire, it may indicate that the alternator is getting to wear out. The alternator's drive belt is closer to its engine that remains hot.

Also, the alternator goes through continuous friction and tension, making it wear-prone over time. And finally, it produces a rubber or wire-like burning smell. Check the alternator and fix it if it’s damaged.

7. Popping Up Battery Warning Light

Checking the battery warning light on the car dashboard indicates battery-related problems. They include alternator failure. Irregular voltage supply and dropped battery capacity. Check the alternator and if you find it damaged, replace it.
