My work was a little special since my car has been modded so heavily, but he had no issues. Did exactly what I wanted done and I even got a pair of wire cutters he left by accident lol. Sorry man! You did an OUTSTANDING job.
The car was a challenge that Tony conquered.

Brandon was absolutely incredible. He arrived early and he worked at a fantastic pace. He ensured that all of the work was completed before the rain began to fall, rather than giving up in fear of a downpour. I would absolutely request him again.
Showed up early and completed the job without a hitch. Made recommendations for other things that needed attention (brakes) that reminded me I needed to tend to them. Overall it was a good job and affordable enough that I would consider using the service again for jobs I am not comfortable performing on my own.

This was my first experience using a mobile mechanic and didn't have high expectations. Charles was by far one of the more experienced, knowledgeable and efficient mechanics I've ever come across. Not only did he have me up an running quickly, he provided so much information that I feel empowered in maintaining my vehicles maintenance. He had impressed me so much I immediately booked him again for more work. Highly recommend his services.

Alternator Repair Service

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.
