Alternator Repair Service & Cost

What is the Alternator all about?

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

Keep in mind:

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.

How it's done:

  • 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:

Ask your mechanic to inspect the condition of the charging system during every major service. 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.

How important is this service?

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.

Patrick is a great guy and really knows his stuff. Yourmechanic.com rips you a new one on parts and labor but i guess you pay for not having the headache. I paid 370 labor for 3 hours and 255 for parts that go for 65 bucks on parksgeek.com and even cheaper on a few other sites but for original bmw parts it is 65 and they charged 255. Fyi. If it can wait a couple days, buy the parts first

Emmette
32 years of experience
Emmette was fantastic! He arrived early. He changed my one of my ignition coils and all spark plugs. When doing so, he showed me an oil leak seeping into the plugs which he explained caused the short. A different repair shop I went to two days prior advised e to change all coils and plugs at a price of $1,100, They never once noticed the leaking oil under the failed coil (and all others). When my car sputtered a bit on initial start up, Emmette insisted I take it for a ride while he waited for my return. He did so to ensure that the repair worked and I was satisfied. Emmette also inspected my entire car on his own accord. He sprayed a squeaky door, adjusted my tire pressure which was excessive (55 lbs of pressure instead of 32 in all 4 tires. This excess was done by a dedicated "tire" shop when they put my new tires on...What the heck!). He also fixed a bent gas cap (which is likely the cause of 2 EVAP leak codes). He did so at no charge, whereas the other shops wanted to replace major EVAP parts at yet another $1, 500. So far, no EVAP code has returned. I was a bit apprehensive having an unkown mechanic outside of a physical shop do the work on my BMW Z3. However after my exceptional experience with Emmette, I'm going to hire him to replace an expansion hose and to further diagnose and fix the oil leak he found.

Michael
23 years of experience
Michael was very professional, called me one day before the appointment to make sure everything was on track. He showed up on time to the appointment with a professional appearance and tools. My car was inoperable upon his arrival and helped me push my 3800 lbs vehicle all the way into the apartment complex. He began inspecting the starter that needed replacement and discovered the previous mechanic had not seated the electrical wiring properly and thus the starter did not need be replaced. Most mechanics would of pulled a shady move and still went ahead and replaced it. Due to his findings he was able to save me money and time! I can't wait to work with him again.
