Model 2JF - 200 silicon rectified dynamo should be used in
co~junction with mo?el FT 70 D regulator and with tlie positive
and negative poles must be connected correctly ,otherwise the
gen~
era tor will be damaged.
(3)Voltage ,Regulator
The functions of model FT 70 D volage regulator are : to
maintain automatically the terminal ~oltage of the generator within
the specifiedlitnit
of
13.· 8 -14. 5'volts when the generator speed

elose or open circuit from the batterytd the exciting
winding of the generator relevantly when the key - switch
IS
turned to, the "on" or "off" position respectively.

Staring Motor
The staring motor. is of model ST95,
DC
series exciting type
with a voltage 'of 12volts and a maximum power output of 1. 47kw.
It
is provided 'with an electro - magnetic e'ngagelTlent mechanism
and a one - way rolling ball clutch to prevent the armature from
damage caused by the high speed rotation after the engine start-
Ing.
After
switching
on the
elec~ron ~
magnetic coil- by mea,ns of
the starting switch , the core of coil- will be pulled in
due' to
the
electro - magerttic action. This drives the starting motor's pinion
to
engag~
withthe flywheel gear ring through the actuating lever;
in the t;tleantime, the starting motor circuit is' switched on,causing
the motor, then the
fly
wheelrotate.T.~rJiing
off the"'sta-r:ting
switch ,the power supply of the electro-magnetic coil is cutoff,
the magnetic force disappears, the core will return to its original
pqsit.ion. This causes the starting
motor~spinion
to disengage with
the flywheel gear ring.. At ·the same time, the power supply will be
cut off to stop the ,starting motor rotating.
