Ford Taurus

I have a 98 Taurus with 89k on it. My battery light comes on when I am
accelerating. My lights dim and my blower motor slows. Once I get up to
speed and the rpm's drop back the lights may come back to normal, but not
always. Sometimes I have to slow down for the lights to come back up.
What could cause this? I've checked the serpentine belt and alternator.
They seem fine.

Re: Ford Taurus

That sounds like what happened when my alternator was going bad, have
you checked the voltage it is putting out?

"They seem fine."
I think he means they were still there. The belt was black. The
alternator was silver and not rusty looking. That should work, right?
He kind of suspects the alternator, but that would cost lots more than
cleaning a cable or something.
Sorry Dave, the next step is to check the charging circuit with a meter
on you way out to the parts store or repair shop.

Take your alternator someplace they will test it. Have the battery
checked too.
When you buy a new alternator, don't get the cheapest thing
Autozone has. I bought two with one year guarantees. First
one lasted 14 months, second lasted 13.
They are GUARANTEED to die with your wife and kids in
the car, when you are not around.

Um, yeah. Seem fine? Milk from last July in the fridge is still white,
too. Knock yourself out. Go to your friendly car parts store and see if
they'll check the alternator. I'll betcha a cuppa fivebux coffee that it's
on its way out.

Happy alternator swapping!

Actually it is always a good idea to check for dirty cables first. They are
cheap and can cause problems with charging for sure.

Re: Ford Taurus

Thanks to everyone for the advise. I did replace the alternator and it
seems to have fixed the problem.
