When the ignition
voltage relay points " P o " and M P 1 M, through the ch arge warning light, therefore,
the charge warning light g lo w s. A t the same time, the exciting current from the
battery flows to the rotor coil through the fuse fo r the turn signal, voltage r e ­
gulator points " P L 1 1 1 , " P L o 1 1 , brushes and the slip rings, causing the rotor to
magnitize.
In these condition, as the rotor is rotated, the three-phase alternating current is
generated within the stator coil, and the alternating current is fully rectified into
