OPERATION

When

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

to
