OPERATION OF DYNAMO
The dynamo consists of a series of permanent magnets that rotate around a stationary stator coil. The
magnets are attached to the flywheel which is rotated via the engine cooling fan drive belt. The resultant
output is an AC (alternating current) signal. The AC is converted to DC (direct current) by the current
limiter. The current limiter outputs charging DC current to the battery.
