Where is the alternator located in a car?
The alternator is an electrical device situated in the engine bay tasked with generating electricity to charge the battery of the car. It is coupled to the engine drive, meaning that when the engine is activated the alternator is actuated, in turn, the battery is charged.
Can a car alternator voltage regulator be trusted?
If the functioning of a traditional car alternator voltage regulator is analyzed, we find it amazing that these kinds of regulators is often as trusted as they are.
How much do alternator repairs cost? It depends if a repair is possible. If not, you’ll have to have it replaced, which can run between $500 to $1,000 (including parts and labor).

What fails in an alternator?
One of the most common failures is bearing failure. The needle bearings that allow the rotor to spin freely inside the stator can break down from dirt and heat. When the bearings fail, the rotor will not spin efficiently and can eventually seize. Usually an alternator with bearings failure makes a loud grinding noise.

Why is my alternator not working in my car?
Keep in mind that many failures in the charging system can also be the wiring between the alternator and the battery, but it’s best to always start with the alternator. Because the alternator supplies current to the vehicle’s electrical systems, this is where you’ll notice most that something is amiss.
