What are the four wires of a Toyota generator?

[Damian]

Toyota generator's four wires are the excitation wire, neutral wire, ground wire, and speed output signal wire. Here are the specific introductions about automotive generators: 1. Function: The automotive generator is the main power source of a vehicle. Its function is to supply power to all electrical devices (except the starter) when the engine is running normally (above idle speed), while also charging the battery. Based on the three-phase stator winding of a regular AC generator, it increases the number of winding turns and introduces lead-out terminals, adding a set of three-phase bridge rectifier. 2. Principle: When the external circuit energizes the excitation winding through brushes, a magnetic field is generated, magnetizing the electrodes into N and S poles. When the rotor rotates, the magnetic flux alternates in the stator windings. According to the principle of electromagnetic induction, alternating induced electromotive force is generated in the three-phase windings of the stator.
