The lights dim when I'm at a stop and turn the steering wheel. I have a new battery, could it be the alternator?

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! Light's dimming? Let's brighten your day! There is a definite possibility that the alternator is failing. The fact that the lights are dimming when you're turning the wheel may be indicative of the serpentine belt slipping in turn not allowing the alternator to charge properly. If the alternator is failing, it may not be providing enough power to the electrical system, causing the lights to dim when the steering wheel is turned or when the car is idling. Either way, I'd recommend having the alternator checked by a mechanic to confirm the diagnosis and replace it if necessary. If you have any other questions feel free to call us at 877-913-1554!
