Alternator/Charging System
The charging system consists of an alternator and a
rectifier/ regulator assembly and the battery. The
alternator is made up of two parts, the stator, which is
mounted to the crankcase or the engine cover, and the
rotor, mounted to the end of the crankshaft. The stator is
an assembly of 18 coils, arranged into 3 phases. The rotor
is a series of magnets mounted in the engine flywheel,
which are arranged so ·as to be positioned around the
outside of the stator coils. As the engine rotates the
alternator produces an ac <alternating current) voltage in
each of the three phases of the alternator, typically of
around 35 to 40 volts ac at 4000-5000 rpm, although
this figure varies between models. As the battery requires
de (direct current) voltage for correct charging, this ac
voltage must be first rectified to de current, and then
regulated to the correct voltage for the battery of
14.5±0.5 volts. This is done by the rectifier/regulator,

General Information
which uses diodes to convert the alternator output to
de volts and limit the resulting output to the correct figure
required for optimal battery charging.
If the charging circuit does not operate correctly, the
following basic checks must be carried out before further
diagnosis is performed:
Check the battery terminals are clean and
tight.
Check the frame and engine earth
connections are clean, tight and free from
corrosion.
•
Ensure the battery is fully charged and in
good condition.
Check that any fuse in the circuit is not blown
and is of the correct rating <See page 17- 1 1>.
Rectify any defects as necessary.
