I had the same probelm with my 1994 3.8 Taurus. Took it into Ford Dealership for repair. They first checked fuel pressure and it was ok.But they found a problem with the idle air control valve. Must be replaced can't be fixed or repaired(cost about $140 cdn for part)It sits on top of the engine Ford Part number cx-1854 (f68z-9f715-eb). take care I had the same probelm with my 1994 3.8 Taurus.

replace the voltage regulator
Not very. Leo doesn't like how stubborn Taurus is, and Taurus doesn't like how Leo tries to be in charge of everything. It wouldn't work out.
defective voltage regulator
faulty voltage regulator
If the regulator is bad, the alternator would have a low charge or a high charge or no charge at all. With a good battery that is fully charged (12.68 volts) and the engine warmed up and idling with no accessories on, you should get a voltage reading at the battery of 14.2 v (plus or minus .2 v).
Bad voltage regulator
A voltage regulator converts a/c volatge from the stator to dc voltage and regulates it down to under 15 volts. When they go bad they can over charge and take out a battery as well as not charge at all.
regulator is bad inside alternator
The voltage regulator is faulty.
Charge voltage is controlled by the computer
The alternator, in cooperation with the voltage regulator and the charge relay.
Defective alternator or internal voltage regulator is bad.
No, the voltage regulator determines the alternators output voltage. That's all it does. If the regulator fails the battery level can drop to the point that there will not be sufficient charge to start the engine, but the regulator will not directly cause the engine to not run.
A bad belt, a bad regulator in the alternator or bad brushes in the alternator.
Have you checked the fuses?AnswerMay be a bad voltage regulator. alternator is no good without a voltage regulator. that's what "turns on" the alternator.
either it does not charge the battery enough or it will charge it too much which will quickly cause the electrolyte in the battery to evaporate
You can't change the charge because that is changing the very chemical nature of the ion/atom. To make formulas with ions, you use subscripts to change the NUMBER of ions in the formula without changing the CHARGE.
no it will only make the battery not charge
have the battery checked and test the voltage regulator
bad pcm regulator
charge through a pressure regulator
The voltage regulator for the alternator is in the computer. If the voltage regulator in the computer does not work, you can add an external voltage regulator and then your battery will charge normally. Make sure to check the ground on the computer. If the ground is bad on the computer, then the computer will not regulate the voltage to the alternator properly.
Bad battery won't take charge Bad battery cables Fuseable link
The voltage regulator on a 1986 Buick Skyhawk is located inside the alternator. It controls the amount of power sent to charge the batter based on its current state.
