Charging
When the ignition key is turned to position II (and III) current goes from the central electronic module to connection L on the charge regulator. The regulator directs current to the excitation winding rotor and is then grounded via the regulator. When the current travels through the rotor a magnetic field is formed around the rotor. When the engine is started and the rotor begins to rotate, the magnetic field also rotates and then produces alternating current in the stator windings.
Alternating current is rectified when it passes the diodes and is then fed to the electrical system of the car. The voltage obtained from the stator winding also passes to the regulator via the rectifier and affects the control functions.
When the voltage exceeds the permitted value, the charge regulator reduces the current through the excitation winding. The strength of the magnetic field decreases as does the stator winding supplied alternating current.
The charge indicator lamp in the combined instrument panel is controlled by the driver information module via signals from the Controller area network (CAN).
