The alternator in your car is one of the essential parts without which the car cannot perform properly. The job of an alternator is to preserve the battery’s power while the car use power from the battery to generate lights and any other electrical systems. Therefore, if the alternator fails to function, it will be a real headache for the driver.
Let’s check out 6 signs telling your alternator is maybe running into problems.
1. Fainted lights
The alternator works to give power to the ignition, starter and electric accessories. A weak alternator provides less power to these needed parts including light systems which will become fainted when the alternator becomes weak.

3. Weak or dead battery
As said above, the alternator works to charge, then restore your battery’s power, so when your car battery is low, the alternator can't help.
To figure out if the problem is in the battery or the alternator, charge your battery and start your car.

5. Crunching sounds
There are plenty of parts spinning inside the alternator. When one of these fails, there comes a crunching noise.
