b.
Start both
engines
according
to
the
engine
start
procedures
in the
applicable
Pilot’s
Operating
Handbook.
c.
Place
both
alternator
switches,
located
on
the
pilot’s
subpanel
to
the ON
position.
CAUTION:
Monitor
the
cylinder
head
temperature
indicator
to
prevent
overheating
of
the
engine
due
to
inadequate
air
cooling.
d.
Bring
the
alternator
control
unit
and
alternator
up
to
operating temperature by
running
the
engines
for
at
least
5
minutes
at
a
minimum
of
1200
rpm
with
the combined
readings
for both loadmeters
indicating
a
TOTAL electrical
load
of
30%.
e.
Record the
bus
voltage
while
running
the
engines
at
1200
rpm.
NOTE: Do
not
use
the voltmeter
on
the
airplane
instrument
panel
except
to
determine that
the
alternator
is
operating.
f. Turn
the
right
alternator
offand
record
the bus
voltage.
Turn
the
right
alternator
on
and
the left alternator
off
and
record
the
bus
voltage.
With both alternators
on,
check
for
a
bus
voltage
of
28.5 0.3
vdc and
record.
The
difference
between
the
readings
just
recorded
should
not
exceed
0.25
vdc.
g.
If
adjustment
of
the
left alternator
is
required
shut
down
the
right
engine
and
adjust
the left alternator
control
unit
(located
in
the
nose
baggage
compartment)
output
to
match the recorded
voltage output
of
the
right
alternator.
h.
If
the
right
alternator
control unit
requires
adjustment,
shut
down
both
engines
and
adjust
the
right
alternator
control unit
in
small
increments.
NOTE: Due
to
the
location
of
the
right engine
propeller
to
the
nose
baggage
door,
both
engines
should
be
shut
down
when
adjusting
the
right
alternator
control unit.
i.
Start
the
right
engine
according
to
the
engine
start
procedures
in the
applicable
P.O.H..
j.
Place
the
right
alternator
switch
to
the
ON
position.
k.
Bring
the
alternator
control
unit and alternator
up
to
operating
temperature
and record the bus
voltage
while
running
the
engine
at
1200
rpm.
i.
Start
the
left
engine
according
to
the
ENGINE
START
procedures
in the
applicable
Pilot’s
Operating
Handbook.
m.
Place the
left
alternator
switch
to
the
ON
position.
n.
Bring
the
alternator
and
alternator
control
unit
up
to
operating
temperature by
running
the
engines
at
minimum
of
1200
rpm
with
the
combined
readings
of
both
loadmeters
indicating
a
TOTAL
electrical load
of 30%.
o.
Check
the
voltage
and
load
readings
on
the
applicable
volt
and
load
meters.
If
the
voltage
on
both
alternators
does
not
indicate
28.5
0.3
vdc and
the
load
is
not
shared
approximately
equal
between
alternators,
the
adjustment
procedure
will have
to
be
repeated.
