Lucas

Always reluctant to hire a new mechanic - but Lucas was thorough, professional, knowledgeable,helpful, friendly, courteous. He went straight to work, isolated my problems, gave me fair and reasonable quotes. I will keep his card and probably keep him busy. My car was a pass down from my father - 16 years old, 200,000 miles and in need of some TLC. Lucas is my guy! Highly recommended.

Tom

Had an amazing first experience with Tom. I've already told my neighbor, my brother, and my Dad they need to start using him. Did an incredible professional job, even stepped me through the process so I can do it myself next time. It was very reassuring watching Tom work and seeing everything come apart and put back together with the new parts. YourMechanic is the opposite of everything that is wrong with the typical mechanic shop. Car drives perfectly now and buying my own parts and having Tom install them saved me a big chunk of change.

All about Alternator Replacement

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.
