FLOOR

TEMPERATURE

WARNING
SYSTEM

DESCRIPTION

The
floor

temperature
warning

system
consists
of
a
floor

temperature

sensing
switch
installed

on
the
vehi

cle
s
floor
floor

temperature
relay
and

a

warning

lamp
on
the
instrument

panel
and
wires
that
connect
these

parts

When
the
floor

tempera
ture
rises
to

an
abnormal
level
the

warning
lamp

will

light
to
call
the
attention
of
the

driver
The

wiring
diagram
of
this

system
and
location
of
the

floor

are

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
