has
opened,
the

seconds.
If
the

When
the

As
soon
as

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

o
f
relay
G426,
fuse

and
wire

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.

IC.
The

If
