Battery Dash Light On Runs Bat New Help

What year??Sometimes other year models have specific problems..
But the other thing is to check Alternator,Cables connection to starter from Battery. And Body ground Connection.. Connection to alternator.

More than likely if the belt isn't broken the brushes in the alternator have worn so much that the springs will no longer hold them against the armature with enough force to carry current. You can get new brushes that go in for about $12. Push the new brushes back aginst the springs and insert a pin or paper clip or tooth pick in the hole to keep them retracted. After installation just pull the pin out and the brushes will snap against the armature.
