connected in series with an output of 20 W at a
voltage of 6 V.
1. Alternator
Electric current is supplied by the alternator
Another stator coil supplies current to the ignition
fitted with a rotor with permanent magnets. The
coil and the thyristor block controlled by the
lamps are fed with current from three stator coils
