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

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

permitted
to
overrun
the
clutch

Inspection
Use
an
ohmmeter
as
shown
in
Fig

the
tester
between

slip
rings
and
check
that
the
resistance
is
approximately
4
4
ohms
at
normal
ambient
temperature
Check
the
conductivity
between
slip
ring
and
rotor
core
as
shown
in
Fig
M
22
if
conductivity
exists
the
field
coil
or

ring
must
be
earthing
and
the

assembly
should
be

retween
the
individual
stator
coil
terminals
as
shown
in
Fig

If
there
is
no
conductivity
between
the
individual
terminals
the
stator
is
defective
Check
each
lead
wire
including
the
neutral
wire
as
shown
in

If
there
is
conductivity
between
any
wire
and
the
stator
COTe
the
stator
core
is
earthing
and
the
stator
must
be
replaced
Diodes
Three
positive
diodes
are
mounted
on
the
positive
plate
and
three
negative
diodes
are
mounted
on
the
negative
plate
The
diodes
allow
current
to
flow
in
one
direction
only
The
diodes
on
the
positive
plate
only
allow
current
to
flow
from
the
terminal
to
the
positive
plate
whilst
the
diodes
on
the
negative
plate
only
allow
current
to
flow
from
the
negative
plate
to
the

A
diode
which
allows
current
to
flow
in
ooth
directions
or
does
not
allow
current
to
flow
in
the
correct
direction
is
unserviceable
and
all
six
diodes
must
be
replaced
Use
a
tester
as
shown
in

to
check
each
diode
Brushes
Check
the
