CAUTION:
If the
adjusting
screw
is turned down
(clockwise)
beyond
the
normal
adjustment
range,
the
spring
support
may
fail
to
return
when
pressure
is relieved. in such
case,
turn
the
screw
counterclockwise
until
sufficient
clearance
develops
between
the
screw
head
and the
spring support,
then bend
the
spring
support
upward
carefully
with
small
pliers
until
contact
is
made with the
screw
head.
Final
setting
of
the
unit
should
be
approached
by
increasing
the
spring
tension,
never
by
reducing
it. If
the
setting
is
too
high,
adjust
the
unit below
the
required
value,
and then
raise
the
value
to
the
exact
setting
by
increasing
the
spring
tension.
e.
Check
the
voltage
reading
on
the voltmeter.
If
the
reading
does
not
indicate
28.25
rt
0.25
vdc,
gain
access
to
the
voltage
regulator
by
removing
the small
access
plate
on
the
outboard
side
of the left
nacelle,
just
aft
of the
engine
cowi
door.
Remove
the
voltage
regulator
cover
and
turn
the
voltage
adjusting
screw
clockwise
to
increase
the
voltage
reading
and counterclockwise
to
decrease
the
voltage.
NOTE:
The
voltage
regulator
cover
must be
replaced
and
the
voltage regulator
must
be
brought
up
to
operating
temperature
again.
Variations
in
the
temperature
will
effect
the
voltage
reading.
The
voltage
regulator
cover
must
be
replaced
and
the
voltage
regulator
must
be
brought
up
to
operating temperature
again.
Variations
in the
temperature
will
effect
the
voltage
reading.
f.
Replace
the
voltage
regulator
cover,
reduce
the
left
generator
speed
until
the
relay
points
open
and
then
bring
the
generator
back
to
minimum
cruise
rpm.
Check
the
voltage
reading
on
the
voltmeter.
If
the
voltage
reading
I
does
not
indicate
28.25
~t
0.25
vdc,
repeat
the
adjustment
procedures
for
the
left
voltage
regulator
until
it
does.
g.
Replace
the
small
access
plate

h.
Place
the
right
generator
switch
in
the
on
position
and
the
left
generator
switch
in
the
off
position.
i.
Bring
the
voltage
regulator
and
generator
up
to
operating temperature
by
running
the
engine
for
at
least
20
minutes
at minimum
cruise
rpm
with
approximately
15
to
20
percent
electrical
load
as
indicated
on
the
respective
loadmeter,
located
in the
center
section
ofthe instrument
panel.
j.
Again
check the
voltage
reading
on
the voltmeter.
If
the
reading
does
not
indicate
28.25

vdc,
gain
access
to
the

regulator
by removing
the
small
access
plate
on
the
outboard
side
of the
right
nacelle,
just
an
of
the
engine
cowl door.
Remove
the
voltage
regulator
cover
and
turn
the
voltage adjusting
screw
clockwise
to
increase
the
voltage
reading
and counterclockwise
to
decrease
the
voltage.
CAUTION:
