Charging system trouble on 2007 Ford Taurus SEL
My daughter just bought a 2007 Ford Taurus SEL and
after driving it for about 5 days the charging system light
came on. I brought the car to auto zone and they tested
the alternator and said it was bad, so I put a new
alternator in and after 4 days of driving the car the
charging system light came on again. I brought it to Auto
Zone and the alternator was fine, but the battery was bad,
so I bought a new battery and replaced it, after my
daughter drove the car for about 2 days the charging
system light came on again. My wife brought the car to
Auto Zone and they tested the alternator,battery,and
fuses, and told my wife that the battery was only half
charged and that all the fuses were good, but something
is drawing the battery. So I put the battery on a trickle
charger and took a look at the battery cables and
terminals, there was quite a bit of corrosion so I bought
brand new cables with terminals and put them on. After
the battery was charged I took the car out for a test drive
and it drove a little rough and after about 30 minutes the
charging system light came back on again! My thought is
that the alternator must not be charging the battery, but
I'm not quite sure what my next step should be. I'm
starting to think that maybe the PCM is bad and that I
need to replace it. I would love to hear anyone's advice on
what I should do next, I'm getting frustrated trying to
figure out what's going on and my daughter heads to
college in 3 weeks so I need to get this charging system
problem figured out ASAP!
Thank you in advance for everyone that helps me trouble
shoot this problem, I REALLY appreciate it!
