    Bad battery cables if theyre corrode or a loose connection. Take them loose from the battery and clean with a wire brush or whatever you have. Make sure the cables are bolted down tight enough when you put them back on.

  • Have the battery tested. As they age, the actual charge capacity decreases. If the battery is sulfated, it is just that much worse. If the battery has ever gone dead on you, the battery will never have the same full charge.

    Clean all battery leads and grounds and the pos on the starter.
