ADMIRAL CONTROL PANEL
DESCRIPTION
This manually-operated control panel is equipped with a
KEY switch and RPM gauge with an ELAPSED TIME
meter which measures the engine's running time in hours and
in 1110 hours. The panel also includes a WA1ER 1EMPER-
ATURE gauge which indicates water temperature in degrees
Fahrenheit, an OIL PRESSURE gauge which measures the
engine's oil pressure in pounds per square inch, and a DC
control circuit VOLTAGE gauge which measures the sys-
tem's voltage. All gauges are illuminated when the key .
switch is turned on and remain illuminated while the engine
is in operation. The.panel also contains two rubber-booted
pushbuttons, one for PREHEAT and one for START.
RPM GAUGE: REGIS-
TERS REVOLUTIONS
PER MINUTE OF THE
ENGINE AND CAN BE
RECALIBRATED FOR
ACCURACY FROM THE
REAR OF THE PANEL.
HOURMETER:
REGISTERS ELAPSED
TIME, AND SHOULD BE
USED AS A GUIDE FOR
THE MAINTENANCE
SCHEDULE.
WATER TEMPERATURE GAUGE: THIS GAUGE IS
GRADUATED IN DEGREES FAHRENHEIT AND IS
ILLUMINATED WHILE THE KEY SWITCH IS
TURNED ON. THE ENGINE'S NORMAL OPERATING
TEMPERATURE IS 170" -190" F (77"-BB"C).
When the engine is shut down with the key switch turned off,
the water temperature gauge will continue to register the last
temperature reading indicated by the gauge before electrical
power was turned off The oil pressure gauge will fall to zero
when the key switch is turned off. The temperature gauge
will once again register the engine's true temperature when ·
electrical
po~er
is restored to the gauge.
A separate alarm buzzer with harness is supplied with every
Admiral Panel. The installer is responsible for electrically con-
necting the buzzer to the four-pin connection on the engine's
-~lectrical
harness. The installer is also responsible for installing
the buzzer in a location where it will be dry and where it will
be audible to the operator should it sound while the engine is
running. The buzzer will sound when the ignition key is turned
on and should silence when the engine has started and the
engine's oil pressure rises above 15 psi
(1.1
kg/cm
2 ).
OIL PRESSURE GAUGE: THIS GAUGE IS GRADU-
ATED IN POUNDS PER SQUARE INCH (PSI) AND IS
ILLUMINATED WHILE THE KEY SWITCH IS TURNED
ON. THE ENGINE'S NORMAL OPERATING OIL
PRESSURE RANGES BETWEEN 30-60 psi
(2.1 - 4.2 kg/em').
KEY SWITCH: THE KEY
SWITCH WHEN TURNED
ON SUPPLIES DC POWER
TO THE INSTRUMENT
PANEL CLUSTER, PREHEAT
SWITCH, EXCITATION
TERMINAL OF THE DC
CHARGING ALTERNATOR
AND TO THE ALARM
BUZZER ENERGIZING IT IN
A PULSING MODE.

PREHEAT BUTTON: WHEN DEPRESSED, IT CLOSES ·
THE CONTACTS IN THE PREHEAT SOLENOID SENDING
POWER TO THE GLOW PLUGS. THE "I" TERMINAL ON
THE PREHEAT SOLENOID ALSO RECEIVES POWER AND
THIS IS TRANSMITIED TO THE ELECTRIC FUEL PUMP. ·
DC POWER IS ALSO TRANSMITIED TO THE START
BUTTON.

COOLANT TEMPERATURE ALARM: AN ALARM BUZZER HAS BEEN
REACHES 210" F (99"C), THIS SWITCH WILL CLOSE SOUNDING THE
ALARM WHICH WILL EMIT A CONTINUOUS SIGNAL.
START BUTTON: WHEN PRESSED, ENERGIZES THE
STARTER'S SOLENOID WHICH CRANKS THE ENGINE.
THIS BUTTON WILL NOT OPERATE ELECTRICALLY
UNLESS THE PREHEAT BUTTON IS PRESSED AND HELD
AT THE SAME TIME.
OIL PRESSURE ALARM: AN OIL PRESSURE ALARM SWITCH IS
LOCATED OFF THE ENGINE'S OIL GALLERY. THIS SWITCH MONITORS
THE ENGINE'S OIL PRESSURE. SHOULD THE ENGINE'S OIL PRESSURE
FALL TO 10- 5 psi (0.7- 0.4 kg/em'), THE SWITCH WILL, OPEIN 'SOUND-
ING THE ALARM. IN THIS EVENT, THE ALARM WILL EMIT A PIJ[SATING
SIGNAL.
