Built into the alternator.
Inside the alternator
The voltage regulator on this car is part of the alternator and is easily removable with 3 screws.
It is internal, in the alternator
I believe that is in the back of the alternator
Located inside the alternator
The voltage regulator is locate in one of two places. ***The voltage regulator is located in the alternator if you have an IAR type alternator*** ***The external voltage regulator (for the EVR-type alternators) is located on the driver's side wall, right next to the battery. It's much easier to see and/or remove if you remove the battery first. It has "Motorcraft" in raised lettering across the front*** I just had to remove mine.
Unless things have changed, the diodes are part of the alternator. The voltage regulator is attached to the alternator but the diodes are part of the alternator.
You will destroy the voltage regulator if you unplug the battery while it is running, then you will have to replace the alternator anyways.
Needing the location of the flasher on a 2004 Taurus
you may have a bad battery or a bad voltage regulator
No they do not
