1.D+: Threesome. (diode), three low-power magnetic field diode terminals, provide continuous excitation current for the rotor.
2. B+ (POS/+): The positive output terminal is connected to the positive terminal of the battery and the electrical devices (charging) of the vehicle. less the B+ motor is directly connected to the air conditioner.
3. E: negative output terminal, connected to the negative terminal of the battery. Two-wire motors have a B terminal.
4. W (R/IC): phase output terminal, the output voltage is half of the voltage of B+ output and can be connected to a tachometer, AC or DC relay. relay.
5. N: The neutral point of the generator stator winding.
6. IG: Connect to the IG position of the ignition switch, which usually powers the generator regulator and field coil.
There are generally 6 types of grounding marksat the rear end of automobile generators: B, F, N, L, D and S.
1. B is the general power output line;
2. F is the magnetic field terminal, which is used in ordinary alternators;
3. is The neutral point terminal is connected to the neutral point of the star-shaped winding inside the alternator;
4. L is the charging indicator terminal, for the built-in alternator;
5. D is the charging light terminal, which connects the ignition switch and the charging light; 6. Terminal S is the battery voltage detection line.
