Security light

Hi, I'm one of the auto experts on RepairPal's Car Genius team! Great question! Has the alternator already been replaced and the light is still staying on? If not, it makes sense that the light is on due to voltage supply issues. If you have already replaced the alternator there could be something in the system that needs to be reset or reinitialized after the loss of power. I would bring it back to whoever did the alternator, or get it checked out by a reputable shop to determine the cause. If you need any further advice or would like help finding a trusted RepairPal shop in your area or even getting an appointment booked, please feel free to call us at 877-913-1554 or check out https://repairpal.com/certified
