My battery light on my car was on the other day and than my car would not start. We took in to a auto store to be read and charged. They couldn't not charge it. So we replaced it with a new battery. But my battery light is still on and will not go off.
Is the belt turning the alternator?
I would get it looked at soon before your alternator kills your new battery. Get a voltmeter and check the voltage while the car is running both on the AC and DC setting or take it too Sears they will diagnose it for free.
Have your alternator checked but you also need to check you battery cables. Make sure all the connections are clean and tight and that the wires aren't exposed anywhere. If the negative cable is loose or isn't correctly grounded, the power cable will drain the battery.
Take it back to auto shop and have them read the charging system and see if the alternator is putting charge into the battery.If not replace alternator they sometimes won't put enough charge into system also check the belt make sure its tight. hope this helps
