Alternator repair and services

The alternator provides electricity to different components in your car, including your air conditioner and dashboard lights. Any additional power created by the alternator is stored for later use in your vehicle's battery.  A malfunctioning alternator will not charge your vehicle battery.  Your vehicle will eventually run out of battery life and not be able to start.

There could be several causes to a bad alternator. If you need to jump start your battery frequently, or the new battery you just purchased is not holding a charge, it could be a side-effect of a bad alternator. 

This situation is often misdiagnosed as a result of a bad battery, especially if it’s an old one. However, you can save both time and money by getting your vehicle serviced properly by our experienced technicians as soon as possible to avoid further disrepair.  After all, the cost of a repair is minimal compared to replacing a car these days.  It just make sense to take care of your vehicle.

We'd like to be your trusted garage as we are for countless others, where our friendly staff will welcome you.

When you choose O’Brien Tire & Auto Care, we’ll take care of you and your vehicle from start to finish. Our facility is clean with a comfortable waiting lounge and COMPLIMENTARY refreshments and wi-fi.  In most cases, you'll receive same-day services as your appointment.
