For a week or two i was hearing a whining sound from the jeep. last night my check gauge light came on and the needle display for the battery plummeted to 0. the cd player started to sound like it was skipping and after playing with the buttons the radio died out completely.. the interior display lights all seemed to go very dim and the power windows were sluggish. the battery is new so i dont think that its likely the batt. suggestions.? alternator comes to mind.
