BATTERY CHARGING EQUIPMENT
GENERAL
The battery charging
'equipment
(Fig.
0.1/1)
in·
eludes the
following
units: alternator, voltage
regulator and battery charge warning
light
relay.
A red warning light, which is installed on the in·
strument
panel, signals trouble in the system.
For each unit,
the
present chapter
will
give the
necessary
constructional
and
functional
features,
instructions
for
check-up
and
overhauls as well as trouble-shooting informa-
tion
for the charging equipment.

ALTERNATOR
The 1130 type alternator (Fig.
0.1/2)
is a 3-phase,
self-rectifying
generator,
consisting
of
the
following
main units:
stator
(Fig.
0.113)
or sta·
tionary
inductor,
the
rotor
(Fig.
0.1/4)
or
armature,
provided
with
two
slip
rings.
It
is
situated on
the
engine
left
side, being driven
from
V-belt on fan pulley. The belt
tension
must
be checked from
time
to
time
and adjusted,
if
re·
quired, after every 200 hours' operation.
STATOR:
The
stator
(Fig. 0.1/3)
consists
of
a structure
of
made up annular
laminations
and provided
with
36
slots.
These accommodate a star connected
3-phase
winding
made
of
electric
wire insulated
by
a
double
layer
of
enamelled polyvinyl. A cable
is
connected
to
the
"C"
terminal in the star
center,
to
which
is connected the battery warn-
ing
light
relay.
