I have a 2004 4.6 118,000 miles, battery light has been on for about 2,000 miles - P0620 generator conditions circuit. My headlights and interior dash lights flicker sometimes. I also have a noise coming from the front of the engine that sounds like a bad bearing in one of the pulleys. Most of the time when I turn the wheel I get a slight whining noise. I thought power steering pump, but I was watching a youtube video which explained that this noise could be caused by the idler pulley and tensioner going bad.
So the question is, could the alternator light and whining noise both be caused by the idler pulley and tensioner being shot?
