Q: Battery light is on

asked by on

The battery light is on.

Hi, this comes up often. Your car battery light being on is an indication that your engine is not getting enough energy. This could be because of a malfunctioning alternator or a battery going bad. I suggest having a certified mechanic, such as one from YourMechanic, come out and test your battery.
