and
the

has
opened,
the

will
be
deactivated
for
60
seconds.
If
the
engine
is
not
started
w

this
time,
the

is
reactivated.
If

When
the

is
switched

and
the

is
in

will
be
energised.

As
soon
as

turns,
the
V

applies
a

is
then
applied
to

Note:
When

CHARGING
C
IRCUIT
If
the
c
ontact
is
a
ctivated,
there
is
v
oltage
on
connection
point
85
of
relay
G
426.
This
relay
is
activated.
V
o
ltage
is
now
applied
to
connection
point

of
the
a
lternator
through
fuse
E037,
contacts
30
-
8

o
f
relay
G426,
fuse
E350
and
wire
1380.
An
internal
resistor
in
the
a
lternator
is
energised
b
y
a
n
IC
in
the
carbon
brush
holder
.
This
resistor
ensures
that
a
low
level
o
f
current
passes
through
the
energising
resistor
.
This
excites
a
magnetic
field
in
the
alternator
.
After
s
tarting,
the
v
oltage
on
terminals
B
+
and
15
will
rise
to
about
28.5
V
.
O
nce
this
v
oltage
is
reached,
the
IC
in
the
regulator
interrupts
the
pre-exciter
c
oil
to
enable
the
voltage
to
be
regulated.
The
m
agnetic
field
w
ill
now
disappear
,
s
o
that
the
generator
will
not
be
energised
for
a
s
hort
period
o
f
time.
As
a
result,
the
v
oltage
on
outputs
B
+
and
15
will
drop.

output.
The
a
lternator
charging
current
warning
lamp
is
activated
v
ia
wire
1020,
which
is
c
onnected
to
the
V
IC
(D900).
T
he
VIC
c
ontrols
the
D
IP
via
the
CAN
network.
T
he
voltage
on
wire
1020
is
switched
by
the
c
ontrol
IC.
The
a
lternator
is
also
equipped
with
a
‘sens
’line.
This
connection
continuously
measures
the
v
oltage
on
connection
point
30
of
the
s
tarter
motor
.
If
the
v
oltage
on
connection
point
30
drops,
the
voltage
is
immediately
c
orrected
by
the
c
ontrol
IC.
The
alternator
will
increase
the
voltage
until
a
value
o
f
28.5V
is
reached
again.
