Being stranded in a parking lot in Des Moines, IA, or on the side of the road in Polk County 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, Chamberlin Automotive will run a diagnostic test, and review the results. If you would like your alternator, or electrical system diagnosed, call Chamberlin Automotive at 515-266-9000, or schedule an appointment online.
