Whine from engine bay 02 Dodge Grand Caravan
I have a 02 Dodge Grand Caravan 3.8L when I start
the van it has a whine. When I drive it whines unless
it is over 40 mph. I have a high ripple from the
alternator. Over voltage and under voltage engine
codes. But when I pull the positive side of the
battery cable off the van still runs. What could this
be? Power steering or alternator?
