Question about 2004 Ford Taurus
Replaced battery, spark plugs and wires, starter, and checked the alternator which is working fine.
Possible a bad regulator. Some alternators have the regulator as part of the alternator and others have it separate. If you did not have the alternator bench tested but simply used a multimeter to check voltage then it is possible that the alternator is not good as you can have 14.5 volts out put but it could be ac current as a rectifier is bad.

With the battery light on and at 14 volts I would suspect that the diode trio is going out and over charging the battery, first check that the battery has fluid in it all the way if it does then have it load tested at a battery shop like all state or sears or any parts store can do a load test for you. Just because it's putting out 14 volts does not mean it's putting out enough amperage, the light is giving you fair warning of an impending problem, have it checked at AutoZone or shucks it does not cost nothing and they can test the alternator output as well.

I found the problem YEAH. It was the fuse that is in the side of the fuse box under the hood, Its where the battery wire from the alternator connects thru a fuse to go to the battery, Its one hundred and something volt fuse. It took care of the problem instantly.... Thank you all for your replies...

SOURCE: Will not charge battery.
Will the battery take a charge, charging it with a battery charger ? Might want to have alternator checked to see if its any good, make sure battery cable connectors are tight, if they arent the battery more than likely wont take a charge.
