OPERATION
When
the
ignition
switch
turned
fully
clockwise
to
the
START
posi
tion
battery
current
flows
through
series
and
shunt
coils
of
the
solenoid
magnetizing
the
solenoid
The
plunger
is
pulled
into
the
solenoid
so
that
it
operates
the
shift
lever
to
move
the
drive
pinion
into
the
flywheel
ring
gear
Then
the
solenoid
switch
contacts
close
after
the
drive
pinion
is
partially
engaged
with
the
ring
gear
Closing
of
the
solenoid
switch
contacts
c
uses
the
motor
to
crank
the
engine
and
also
cut
out
the
series
coil
of
the
solenoid
the
magnetic
pull
of
the
shunt
coil
being
sufficient
to
hold
the
pinion
in
mesh
after
the
shifting
has
been
performed
After
the
engine
starts
running
the
driver
releases
the
ignition
key
and
it
automatically
returns
to
the
ON
posi
tion
The
torsion
spring
then
actuates
the
shift
lever
to
pull
the
pinion
which
allows
the
solenoid
swi
tch
contacts
to
open
Consequently
the
starting
mo
tor
stops
