My battery won't turn over but the radio still works - what is wrong
Battery's don't turn over, engines do. Do you hear clicking? Check the voltage, if it around 12V or lower, you don't have enough Cold Cranking amps, but enough for the lights to come on. You'll need a jump start, and think about swapping the battery for a new one.
Could be an alternator. Check your timing or sepentine belts. See if you can turn the alternator.
