The generator terminal F is the live wire of the generator's magnetic field coil.
The generator is the main power source for automobile electrical equipment. During normal car operation, the alternator powers other electrical equipment except the starter and charges the battery. That is to say, when the engine is running normally, almost all of the car's electrical energy is supplied by the generator.
Excitation method powered by an AC exciter. Some modern large capacity generators use an AC exciter to provide excitation current. The AC exciter is also installed on the large shaft of the generator. The output AC current is rectified and supplied to the generator rotor for excitation. At this time, the excitation mode of the generator is the excitation mode, and a static rectifier device is. used.
Detailed information:
The terminal F of the generator is the wire under generator magnetic field coil voltage. If you don't connect it, it will never produce electricity, because the generator depends on the magnetic field coil to work! The regulator regulates the generator output current voltage.
Since the power generated by the generator is approximately 4V greater than the power generated by the battery, a regulator is necessary. Increase the voltage when the battery is low and stabilize the voltage when the battery is full!
As for the charging light which is always on and flashing, this means that there is a malfunction in your car's charging system. (Specifically include: generator, regulator, charging system circuit)
The reason why the two live wires of the generator are connected togethere can be magnetized because a magnetic circuit is formed. In a generator, when current passes through a coil, a magnetic field is created, and this magnetic field is reinforced by the loop of the iron core. If two live wires are connected together, a complete circuit will be formed and current can flow. This creates a magnetic field that magnetizes the generator. This method is only suitable for certain types of generators and requires special adjustments and operations, otherwise it will pose a safety risk.
