Voltage on alternator is 12

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I'm sorry to hear you're having trouble with your Camry. If your alternator's output is reading 12 volts, that indicates it's not functioning properly. A healthy alternator typically produces between 13.5 and 14.5 volts while the engine is running, which is necessary to charge the battery and power the vehicle's electrical systems. Since you mentioned the alternator has been replaced, it's worth checking all power and ground connections to ensure there are no loose or corroded connections that could be affecting its performance. Additionally, consider checking the battery itself. If the battery is weak or has internal damage, it may not hold a charge properly, even if the alternator is working. Given that the car just started having these issues after driving it for a while, it might also be worth testing the new alternator to confirm its functioning correctly. Getting a professional opinion could save you time and money if you're unsure.
