indications are that either the DC field has been inadver
tently "flashed" in the wrong direction, or that the
generator is operating on residual magnetism only. To
"flash" the field, remove the (A+) lead from the generator
and momentarily close the generator cutout contacts, making
certain that the external connections to the battery are
correctly connected with regard to polarity~
(c) If the ammeter indicates zero charging current
when the generator voltage. is above 13.5 or 26.8 volts for
12 or 24-volt systems respectively, check the operation of
the generator cutout contacts. If the contacts are open,
the unit is out of adjustment and should be reset in accord
ance with manufacturer's cutout instructions. If the contacts
are closed, check th~ charge on the battery, since the charg
ing current drops down to a low value when operating with a
·fully charged battery resulting in li tt~e or no ammeter
indication.
(d) ·· If the AC voltage output is below the normal 120
volts (=5%), check the DC voltage output and readjust to
proper value as instructed under "CONTROL BOX INSPECTION.·"

Before attempting to start the engine for the first time,
the following checks should be made:
(a) At least three (3) gallons of lubrication oil Navy
Specification 1065 t<Y 1080 should be ple.ced in the
oil tarL'l.c.
(b) See that 24 volts of battery are across line and that
the main line switches for auxiliary power plc.nt are
in "off" position.
(c) Inspect magneto ground wires for proper connection.
Notice: Press in on automatic over-sneed cut GUt
button to make sure switch is in oper ating
position.
(d) Fuel tank should contain 91 octane gasoline. Open
valves and check engine dribble valve for flooding.
(e) By aid of the hand crank, turn the engine ·through
two or three revolutions. If abnormal effort is
required, remove a spark plug from each cylinder to
make sure liquid has not collected in the combustion
chamber.
This procedure should be followed whenever the engine has
been idle for a week or more. (See Navy Spec. AN9505a for
prepar ation for storage instructions).

(3) Starting
After the above preparations, the engine may be started
in the following manner:
(a) Turn fuel valve to "ON."
(b) Turn oil . valve to "0N. 11
(c) Close main line switch for auxiliary power plant.
See that generator lead is connected.
(d) Turn starter switch to "ON. n Allow starter to prime
engine with fuel and oil pump with oil.
(e) Turn ignition switch to "BOTH" when oil pressure g2.uge
· registers pressure.
(f) Turn starter switch to 11 0FF" as soon as engine fires.
(g) As soon as engine starts, observe the oil pressure
gauge and shut engine off immediately .lf' pressure
is not indicated. N9rmal oil pressure is 55-65 lbs.
per sq. inch.
(4) Manual Starting
If no 24-volt battery source is avail able, the engine may
be started with the hand starting drum.

(5) Warm Up
Vfuen the operating temperature is below 21°C the engine
will idle at about 1800 RPM after starting. As the oil warms,
the engine speed will gradually increase to 4200 RPM (no load).
The governor is adjusted at the factory to operate betweeen
4000 (full load) and 4200 RPM (No load). During warm-up the
engine oil hea.ter should be turned to "ON." Normal operating
oil-in temperature should be about 60°C. and should not be per
mitted to exceed 87°C. DO NOT USE OIL HEATER BEFORE STARTING
ENGINE.
(6) Loading
Load may be applied to generator as soon as the engine
comes up to speed.
(7) Overload Caution
The generator is rated at 5 K.W. (175 amp.) for contin
uous operation. It has an overload capacity of 7.5 K. W.
(263 amp.) for a 5 minute period.
CAUTION: DO NOT operate the power plant above the normal
5 K.W. load for more than five minutes at a time.
Allow 10 minutes at not more than o% loa.d
between overload eriods for the
