What does F mean on voltage regulator?
What does F mean on voltage regulator?
F=field terminal, simply a wire going from the F terminal to the field terminal of the alternator. The regulator varies the voltage on this wire, and that varies the output of the alternator.
What does the stator wire do on a Ford alternator?
The STAtor terminal is connected to coil output before it gets to the diodes, so it puts out an AC voltage. Among its uses are as a tach signal, or to power electric components that can run on AC, such as the choke heater.
What is D on a voltage regulator?
D: (Externally Regulated) This type of connection is used on alternators without an internal regulator. The regulator is normally a separate unit or can be built into the vehicle ECU.
Where does the stator wire go?
In the 65 the stator wire on the alternator runs directly to the S terminal on the regulator, if you do not have a 65 it is not used, on the new models the S terminal of the regulator is connected to the ignition switch (not the alternator). This is assuming you have a wire in the wiring harness for the stator winding.
How does the charging system on a Ford truck work?
The charging system on your Ford truck performs two basic functions: 1. Maintains the battery’s state of charge 1. Connect the positive lead of the voltmeter to the positive terminal of the battery and the negative lead to the negative terminal. 1. Turn off the engine, lights, and all other accessories.
Can a Ford Smart Charge alternator be intolerant?
For this reason, smart charge systems [notably, the Ford system] can be highly intolerant to any alternator that is not manufactured to the original specifications.
What should the voltage be on a fordification Charger?
All the cells should read the same, or within 0.2 volts. If one reads 4.0 or more, you have a shorted cell and the battery is no good. If you get a very low reading or a zero reading, the cell is open and again the battery is no good.
What is the stator wire for on an alternator?
What is the stator wire for on an alternator? The STAtor terminal is connected to coil output before it gets to the diodes, so it puts out an AC voltage. Among its uses are as a tach signal, or to power electric components that can run on AC, such as the choke heater.
What does the charging system do on a Ford truck?
The charging system on your Ford truck performs two basic functions: 1. Maintains the battery’s state of charge 2. Provides power for all of the truck’s electrical systems while the engine is running
It should read about 2.1 to 2.3 volts. Now insert the positive lead in the first cell and the negative lead in the second cell. Proceed down the line until you get to the last cell. Here you will put the positive lead in the last cell and the negative lead on the negative terminal. All the cells should read the same, or within 0.2 volts.
Which is the ignition input that turns on the alternator?
• IG is the ignition input that turns on the alternator/regulator assembly. • S is used by the regulator to monitor charging voltage at the battery. • L is the wire the regulator uses to ground the charge warning lamp.
How does the regulator work in an alternator?
• The regulator is the brain of the charging system. • It monitors both battery and stator voltages and depending on the measured voltages, the regulator will adjust the amount of rotor field current to control alternator output. • Regulators can be mounted both internal or external. Current technology uses an internal regulator.
