bi
metal

arm
and

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
bi
metal

arm
is

bent
and
thus
the

pointer

connected
to
the
bi
metal

arm
is

oper

ated
The
characteristics

of
both

gauges
are
the

same

A
tolerance

may
occur
on
the

water

temperature
gauge
or
fuel

gauge
due
to

source

voltage
fluctuation
The

voltage

regulator
is
used
to

supply
a

constant

voltage
so
that

the
water

temperature

gauge
and
fuel

gauge
operate
correctly

The

operating
part
of
the

regulator

consists
of
a
bi

metal

arm
and

a
heater

coil
When
the

ignition
switch
is

turned
on
the
bi
metal

arm
is
heated

and
bent

by
the
coil

opening
the

contact

Consequently
current
to

the

coil
is

interrupted
As

the
bi
metal

cools
the

contact
closes
The

repeti

tion

of
this

operation

produces
a

pulsating
voltage
of
8
volts
which
is

applied
to
the

water

temperature
and

fuel

gauges

If
both
the
water

temperature

gauge
and
fuel

gauge
become

faulty
at

the

same
time
this

may
be
attributed

to

problem
in
the

voltage
regulator
