Question about 2001 Ford Taurus
CHANGED THE ALTERNATOR BUT IT STILL WONT CHARGE THE BATTERY
Every car ever made has a voltage regulator
The alternator is just that-- AC Current that is rectified
to DC-- to run the car & charge the battery
Just about every car for the last 40 years has the
regulator inside the alt
How it is controlled varies from manufacture,make,
You can not charge a defective battery
You may have external issues that provide
regulator control,even a bad ignition sw on
some cars,or module control of regulator
Need a wiring diagram & a good amount of
knowledge to resolve your current problem

look for a fusible link out. You need to check for output on the alternator that you installed. make sure the batteries are fully charged before that, otherwise its not going to read right. start from the source. also, you can disconnect the batteries from the sys and do a continuity check on the wires in the loom, so you can see if current has a path, or if you have an open circuit. hope this helps

Jump terminals A to F and the alternator should full field and charge. If it charges then replace the regulator. if it doesn't charge replace the alternator. I remember the terminals by thinking of the word AIR FORCE .
