Being stranded in a parking lot in Springfield, MA, or on the side of the road in Hampden is a horrible feeling. A bad alternator can leave you stranded when you least suspect it. The alternator is an important component that charges the battery in your car. It is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. If the alternator is not working properly, even the best car battery will eventually run down. If your battery light is on, your battery has died, or your headlights are dimming and/or flickering, you may have a bad alternator. To diagnose a failing alternator, Bay State Truck Service Inc. will run a diagnostic test and review the results. If you would like your alternator, or electrical system diagnosed, call Bay State Truck Service Inc. at 413-543-5577, or schedule an appointment online.
