How does an alternator help your car run?

The alternator is the component that charges the battery in your car. When you use electrical components in your car (stereo, lights, etc.), the battery loses power. The alternator recharges the battery, replenishing the lost battery power. The alternator is located in the engine compartment. If the alternator is not working properly, your car will only stay running for as long as the battery has power stored. Once the battery loses power, your car will not start. Normally, a malfunctioning alternator will turn on the battery warning light or will have a low volt gauge reading.

Alternator

Before repairing the alternator:

The mechanic should check the entire charging system before installing a new alternator, including checking battery cables for corrosion and the condition of the battery.

Steps when replacing an alternator:

  • Inspect entire charging system (battery, cables, alternator).
  • Inspect the drive belts.
  • Test alternator output.
  • Remove and replace alternator if found to be faulty.
  • Re-test alternator output.

Our recommendation for alternator replacements:

Ask your mechanic to inspect the condition of the charging system during every major service. The mechanic should also clean and tighten the battery cables during every major service.

What common symptoms indicate you may need to replace the Alternator?

  • Dead battery or battery will not hold a charge.
  • Dim lights.
  • Battery warning light is on.

Why repairing your alternator is important:

Your alternator charges your battery, which powers the electronics in your vehicle, such as the radio and the air conditioning. The battery is also needed to turn on your vehicle. A malfunctioning alternator will not charge your car’s battery, and your vehicle will eventually run out of battery life and not be able to start.

BMW 740i V8-4.4L - Brake System Inspection - Chicago, Illinois
Inspected my car and test drove it. Told me exactly what was wrong and showed me the problems. Seems to be very familiar with this type of BMW and knew about some of the problems I've had with it before I even told him. Very happy with his inspection and the advice he provided on how to get everything fixed and how to properly maintain this type of car.

BMW 740i V8-4.4L - Car shuts off when stepping on gas pedal Inspection - San Diego, California
Understood the vehicle and was professional the entire time he worked on it. He diagnosed the problem and helped identify other problem areas that were hurting the cars performance. My car runs exceptionally well now. Next time I'm stuck with a problem and need a mechanic who understands German cars I will call Chet. My car: 1998 BMW 740i 120,000 miles on it. The work done by Chet: chased and diagnosed an electrical problem that was messing up the air fuel ratio causing the car to not operate.
