Being stranded in a parking lot in Citrus Heights, CA, or on the side of the road in Sacramento 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, TOS Auto Repair will run a diagnostic test and review the results. If you would like your alternator, or electrical system diagnosed, call TOS Auto Repair at 916-348-1696, or schedule an appointment online.
