How does a Ford voltage regulator work?
The voltage regulator monitors the voltage coming out of the alternator and, when it reaches a threshold of about 14.5 volts, the regulator reduces the current in the rotor to weaken the magnetic field. When the voltage drops below this threshold, the current to the rotor is increased.
What does F mean on voltage regulator?
An "F" or "FIE" indicates the field terminal. Polarize the generator or alternator through the regulator. Touch one end of the jumper wire to the battery terminal on the regulator. Touch the other end of the wire to the field terminal. Hold it on the terminal for one second, then remove it.
Where is the voltage regulator located?
The voltage regulator is usually found inside or on the back of the alternator case. Increasingly, though, late-model vehicle have the engine control module (ECM) regulating alternator voltage output through a special circuit.
What is the L terminal on a voltage regulator?
As shown in Figure 3, the regulator has an extra terminal marked "L” which is connected with the lower contact point in the cutout relay. This extra ter- minal permits current from the generator to be diverted to the load without its passing through the current-voltage regulator.
What is the F terminal on an alternator?
The alternator F terminal is a duty cycle signal that reflects field operation. The PCM monitors the F terminal to determine the alternator's load on the engine. The PCM uses this information to adjust engine RPM and alternator voltage set point.
Can I bypass a voltage regulator?
If you have a decent power supply and can control the voltage out of it, AND you know what voltage the regulator you're bypassing is supposed to product, then yeah, sure - it's possible.
