DESCRIPTION

A
12
volt

negative
earth
electrical

system
is
used
in
which

the

battery
is

charged
by
an
alternator
In
the
alternator
a

magnetic
field
is

produced
by
the
rotor

which
consists
of
the

alternator
shaft
field
coil

p
le

pieces
and

slip
rings

Output
current
is

generated
in
the
armature
coils
located

in
the
stator
Six
silicon
diodes
are

incorporated
in
the
alternator

caSing
to

rectify
the

alternating
current

supply
A
voltage

regulator
and

pilot
lamp
relay
are
built
in
the

regulator
box

which

nonnally
does
not

give
trouble
or

require
attention

The
starter
motor
is
a

brush

type
series
wound
motor

in

which

positive
meshing
of
the

pinion
and

ring

gear
teeth
are

secured

by
means
of
an

overrunning
clutch

BATTERY
Maintenance

The

battery
should
be
maintained
in
a
clean
and

dry

condition
at
all
times
or
a
current

leakage
may
occur

between

the
terminals
If

frequent
topping

up
is

required
it
is
an

indication
of

overcharging
or
deterioration
of
the

battery

When

refitting
the
cables
clean
them

thoroughly
and
coat

their

terminals
and
the
terminal

posts
with

petroleum
jelly

Check
the
level
of
the

electrolyte
in
the

battery
at

frequent

intervals
and

top
up
if

necessary
to

the
level
mark
on

the

battery
case
with
distilled
water
A

hydrometer
test
should
be

carried
out

to
determine
the
state

of

charge
of

the

battery
by

measuring
the

specific
gravity
of
the

electrolyte
It
should
be

pointed
out

that
the
addition
of

sulphuric
acid
will
not

normally

be

necessary
and
should

only
be
carried
out

by
an

expert
when

required

The

specific
gravity
of
the

electrolyte
should
be
ascertained

with
the

battery

fully
charged
at
an

electrolyte
temperature
of

200C
680F

The

specific
gravity
of
the

electrolyte
decreases
or
increases

by
0
0007
when
its

temperature
rises
or
falls

by
10C
1
80F

respectively

The

temperature
referred

to
is
that
of
the

electrolyte
and

not
the
ambient

temperature
to
correct
a

reading
for
an
air

temperature
it
will
be

necessary
to

add
0
0035
to
the

reading

for

every
50C
above
200C

Conversely
0
0035
must

be
deducted

for

every
SOC
below
200C
Test
each
cell

separately
and
draw

the

liquid
into
the

hydrometer
several
times
if
a
built
in

thermometer
type
is
used

The
correct

specific
gravity
readings
should
be

Always
disconnect
both
terminals
of
the

battery
when

charging
and
clean
the

posts
with
a

soda

solution
Remove
the
vent

plugs
and

keep
the

STARTER
MOTOR
Removal
and
Dismantling

As
previously
stated
the
starter
motor

is
brush

type
series

wound
motor
in
which
the

positive
meshing
of
the

pinion
and

ring
gear
teeth
are
secured

by
an

overrunning
clutch
The
over

running
clutch

employs
a
shift
lever
to
slide
the

pinion
into

mesh
with
the
flywheel
ring

gear
teeth
when
the
starter
is

operated

When
the
engine
starts
the

pL
lion
is

permitted
to
overrun

the
clutch
and
armature

but
is
held
in
mesh
until
the
shift
lever

is
released
An

exploded

of
the
starter

is
shown
in

ALTERNATOR

The
alternator
is
driven

by
the
fan
belt
and
has
an
advant

age
over
a

dynamo
in
that
it

provides
current
at

low

engine

speeds
thereby
avoiding
battery
drain
Maintenance
is
not

normally
required
but
the
tension
of
the
fan
belt
should
be

checked
and

adjusted
if

necessary
as

described
in
the

section

COOLING

Care
must
be
taken
not
to

overtighten

The
alternator

output
can
be
checked
with
the
alternator

in

the
vehicle

by
carrying
out
the

following
test
Ensure
that
the

battery
is

fully
charged
Withdraw
the

gradually
and
note

the

reading
on
the
voltmeter
when
the

engine
reaches
a

speed
of

approximately
lOaD

rpm
The

alternator
is

operating

satisfactorily
if
the
voltmeter
shows
a

reading
above
12
5
volts
If

the

reading
is
below
12
5
volts
the

alternator
is
defective
and
should
be
removed
for

inspection
