FUEL
GAUGE
AND

TEMPE

RATURE
GAUGE

Description

The
fuel

gauge
consists

of
a
tank
unit

located
in
the

fuel
tank

and
fuel
meter
The
tank
unit

detects
fuel
level

with
its

float
converts
fuel
level
variation
to

a
resistance

of
slide
resistor

installed
on
the
float
base

and
thus

controls
current

flowing
to
the
fuel
meter

The

temperature

gauge
consists
of

a
thermorneter
and

thermal
transmitter
located
in

the

engine
block
The

thermal
transmitter
is

equipped
with
a
thermistor
element

which
converts

cooling
water

temperature
variation
to
a

resistance
and
thus
the
thermal
transmitter
controls

current

flowing
to
the
thermometer

The
fuel
rneter
and
thermometer
are

provided
with

bimetal
a
and

heater
coil
When
the

ignition
switch
is

set
to
ON

current
flows
to
the
heat

coil
and
the
heat

coil
is

heated
With

this
heat
the
bimetal
arm
is

bent
and

thus
the

pointer
connected
to

the
bimetal

ann
is

operated

The
characteristics
ot
both

meters
are
same

A

tolerance

may
occur
on
the

thermometer
or

fuel

gauge
due
to

source

voltage
fluctuation
The

voltage

regulator
is
used
to

supply
a
constant

voltage
so
that
the

therrnorneter
and
fuel

gauge

operate
correctly
The

voltage
regulator
is
built
in
the
thermometer

The

operating
part
of
the

regulator
consists

of
a

bimetal
arm
and
a
heater
coil
When
the

ignition
switch
is

turned
on
the
birnetal
arm
is
heated
and
bent

by
the
coil

opening
the

contact

Consequently
current
to
the

coil
is

interrupted
As
the
bimetal

cools
the

contact
closes
The

repetition
of
this

operation

produces
a

pulsating
voltage

of
8V
which
is

applied
to
