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
1/10
hours.
The panel
also
includes a
WA1ER
TEMPER-
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

and
one
for
START.

When
the
engine
is
shut down with the

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 power
is
restored
to
the
gauge.
A
separate
alarm

with
harness
is
supplied
with
