Can the engine light come on when your battery is bad
Can the engine light come on with a bad battery
It takes a lot of battery power to turn the starter motor, but not much at all to light a bulb. Even if the battery is putting out only a few volts, it can still light the lights. If you're having a battery problem, just have it checked. If the car is drivable, drive to a car parts store. If the car isn't drivable, take the battery to the store. They'll check it free.
