DESCRIPTION
Engine Electrical System
REGULATOR
The
regulator
consists
basically of
a
voltage regulator
and
a
charge relay
The
voltage regulator
has
two sets
of

MEASUREMENT
OF REGULATOR
VOLTAGE
Regulator voltage
is measured with
regulator
assembled with alternator
When
measuring voltage
with
regulator
mounted
on
car
it is
necessary
to
rotate engine at high speed
Connect DC
voltmeter
l5 30V
DC
ammeter IS
lOA battery
and
resistor 0 2 5fl with cables
as
shown
I
Check
to
be
sure
that aU electrical
loads such
as
lamps air
conditioner
radio
etc
are
disconnected
2 Before
starting engine be
sure
to
make short
circuit with
a
cable be
tween
fuse side
terminal of resistor
O 25fl and
negative side terminal of
ammeter
Failure
to
foUow this
cau
tion
causes
needle of
ammeter to
swing violently
and
reversely resulting
in
a
damaged ammeter
