I was very skeptical about using this site, would they send someone knowledgeable, reputable, etc. etc... I was very pleased to see that not only did Carlos arrive on time, he was 20 minutes early!! He introduced himself and we discussed the problem my car was having. Carlos came prepared with part in hand and all necessary tools to complete the job. He did his 50 point inspection and took pictures, all the while explaining what and why he was doing things. Carlos had the installation of the alternator done in record time. He made suggestions on future services I would be needing to get done, and wrote it all up in his detailed report. I would Highly recommend Your Mechanic and will be using the service and requesting Carlos again!!

I'm not just giving those high ratings to be nice. Jonathan was very prompt, professional, knowledgeable and friendly. The ignition switch is working great now, and he answered several other general questions I had. I will use the service again. Well, hopefully I don't need it too soon, but when I do, I will use Yourmechanic. Thanks again.

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.
