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
as
follows

Always
disconnect
both
terminals
of
the

battery
when

charging
and
clean
the
terminal

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
view
of
the
starter

is
shown
in

Fig
M

in
a

single
unit
See

Fig

the
washers
can
be

operated
by
turning

in
the

appropriate
direction
It

should
be
pointed
out
that
it
is
inadvisable
to

operate
the
washers

for
more
than
30
seconds
at
a
time
If
the
washers
are

operated

in
short

spells
of

approximately
10
seconds
duration
their

working
efficiency
will
remain

unimpaired
for
a

IGNITION
SWITCH
AND
STEERING
LOCK

The

steering
lock
is
built
in

to
the

goition
switch
When

the

key
is
turned
to
the
LOCK

position
and

then
removed

the
steering
system
is

automatically
locked

by
the

steering
lock

spindle
which

engages
in
a
notch
in
the
collar
on
the

steering

shaft

See

Fig
M
37
The
heads
of

the
screws
are
sheared
off

on
installation
so
that
the

steering
lock

system
cannot
be

tampered
with
If

the

steering
lock
is
to

be

replaced
it
will
be

necessary
to
remove
the
two

securing
screws
