DESCRIPTION
The
alternator
incorporates
an
Ie
voltage
regulator
which
maintains
volt
age
within
the
specified
range
and
prevents
output
voltage
from
rising
higher
than
the
specified
value
Except
for
the
Ie
circuit
alternator
parts
are
essentially
the
same
as
those
of
the
conventional
type
alternator
Service
procedures
outlined
in
this
section
are
restricted
to
information
on
other
than
the
voltage
regulator
In
the
alternator
a
magnetic
field
is
CD
Engine
Electrical
System
ALTERNATOR
produced
by
the
rotor
which
consists
of
alternator
shaft
field
coil
pole
pieces
and
slip
rings
The
slip
rings
pressed
in
the
shaft
conduct
only
a
small
field
current
Output
current
is
generated
in
the
armature
coils
located
in
the
stator
The
stator
has
three
windings
and
generates
three
phase
alternating
current
Silicon
diodes
act
like
a
one
way
valve
for
electricity
so
that
charging
current
passes
easily
but
reverse
current
is
shut
out
In
this
alternator
pack
type
silicon
diodes
are
used
as
main
diodes
Nine
diodes
three
negative
three
positive
and
three
sub
diodes
are
installed
in
positive
and
negative
plates
as
an
assembly
These
diodes
are
direct
soldered
at
their
tips
and
constructed
with
posi
tive
and
negative
conjunction
They
are
mounted
on
the
two
plates
which
combine
the
function
of
heat
dissipating
plate
and
positive
negative
terminals
and
are
light
in
weight
and
easy
to
service

DESCRIPTION
The

circuit
consists
of
igni

dis
tributor

plugs
and
battery
The
distributor
is
of
the
contactless
type
and
is
equipped
with
a
pick

coil
which
electrically
detects
the
igni
tion
timing
signal
in

of
the

I
rea

of
the
conventional
distributor
The
IC
ignition
unit
is
a
new
addition
which
generates
the
signal
required
for
the
make
and
break
of
the
primary
current
for
the
ignition
coil
The
primary
current
is
supplied
by
the
battery
or
alternator
and
flows
through
the
primary
circuit
It
consists
of
the
ignition
switch
primary
winding
of
the
ignition
coil
IC
ignition
unit
and
all
connecting
low

The
secondary
current
is
produced
by
the
ignition
coil
and
flows
through
the
secondary
circuit
resulting
in
high
voltage
spark
between
the
electrodes
of
the
spark

the
secondary

distributor
rotor
and

When
the
ignition
switch
is
turned
on
and
the
distributor
reluctor
rotates
the
primary
current
flows
through
the
primary
winding
of
the
coil
and
through
IC
ignitionu
nit
to

When
the
primary
circuit
is
opened
by
circuit
of

ignition
unit
the
magnetic
field
built
up
in
the
primary
winding
of
the
coil
moves
through
the

This
high

is
produced
every

IGNITfON
CIRCUIT
The
secondary
current
flows
through
the
high

to
the
distributor
cap
then
the
rotor
distributes
the
current
to
one
of
the
spark
plug
terminals
in
the
distrubutor
cap
Then
the
spark
occurs
while
the
secondary
current
jumps
the

and
the

electrode
of

This

is
repeated
for

DESCRIPTION
The
IC
ignition
unit
utilizes
a
semi
conductor
IC
device
and
is
mounted
on
the
side
surface
of
the
distributor
The
IC
ignition
unit
has
the
fol
lOwing
circuits
Spark
timing
signal
monitoring
circuit
This
circuit
detects
the
ignition
signal
sent
from
the
distributor
pick
up
coil
and
amplifies
the
signal
2
Lock
preventing
circuit
This
circuit
cuts
off
the
ignition
coil
primary
current
when
the
ignition
switch
is
ON
and
the
engine
is
sta
tionary
If
the
ignition
coil
primary
current
is
allowed
to
flow
under
such
condi
tions
excessive
current
will
be
drawn
because
of
low
internal
resistance
of
the
ignition
coil

Current
limiting
circuit
This
circuit
controls
the
current
value
so
that
excessive
current
will
not
flow
through
the
power
switching
cir
cuit
To
ensure
efficient
operation
of
the
IC
ignition
unit
these
five
circuits
are
manufactured
in
one
assembly
as
shown
in
Fig
EE

The
semi
conductor
IC
is
utilized
for
all
these
circuits
except
the
power
switching
circuit
The
power
switching
circuit
uses
one
power
transistor
and
the
circuit
is
arranged
on
the
ceramic
substrate
together
with
resislors
capa
citors
and
diodes
Each
component

of
this
unit
is
highly
reliable
however
should
any
part
be
found
faulty
the
entire
