If your car won’t start, stalls unexpectedly, or shows a battery light, you might be dealing with a bad alternator or starter. At Harris Boyz Auto in Iowa City, IA, we provide expert diagnostics and repair for your vehicle’s charging and starting systems. From battery to alternator to starter motor, we’ll identify the issue and fix it right—the first time.
What do the alternator and starter do?
The alternator charges your battery and powers lights, sensors, and other electronics while the engine is running. The starter motor turns your engine over when you start the vehicle. If either fails, your car might not start—or stay running.
