MANUAL
GRIMES
STROBE
LIGHT
SYSTEM
The
system
consists
of
a
solid
state
power
supply
unit,
a
circuit breaker
and
switch
on
the
LH
subpanel,
and
xenon
gas
lights
mounted
in
the
tail and
each
wing
tip.
The
function
of the
Grimes
Strobe
Light
system
is
essentially
the
same
as
the strobe
light
system
described
earlier
in
this Section. Use
that
system
description
for
a more
detailed
explanation
of the
method
by
which the
Grimes
system operates.
The Grimes
System
does
not
incorporate
a
timing
circuit,
since
all the
lights
flash
at
the
same
time
at
a
rate
of
60
flashes
a
minute.

I
CAUTION:
Observe
the
precautions
noted
in the
following
procedure
when
removing
and
installing
the
powersupply.
To
gain
access
to the
power
supply
unit,
remove
the floorboard
on
the
RH side
of
the,
baggage
compartment.
The
entire
unit
may
be
removed
by
disconnecting
the electrical
wiring
to
the
power
supply
and
removing
the
screws
anchoring
the module
to
the
support
structure.
To reinstall the
power
supply
unit,
reverse
the
foregoing
procedures.
STROBE
LIGHT
WIRING
An
incorrect
hook-up
of
the
wires
at
either the
power
input
or
between the strobe
light
assemblies and the
power
supply
unit will
cause
a
reversal
of
polarity
that
results
in
serious
component
damage
and
failure.
Care
must
be taken
to
ensure
that
the
red
wire
is
connected
to
positive
power
and the black
wire
to
ground.
Make
sure
that
the
red,
white,
I
and
black
wires
are
connected
to
pins
A,
B and C of the
connector
respectively
and that
the
connectors
are
properly
assembled.
The
shield
for
wing
cables
should
be
grounded
to
the
airplane
structure
at
the
wing
break
and
the
shield
for
the
tail
light
cables
should
be
grounded
to
the
airplane
structure
at
the
power
supply.
WARNING:
Although
a
bleed-off resistor
is
incorporated
in the
power
Supply
circuit,
high voltage
is
involved
in
the
circuit
between
the
power
supply
and
light
assemblies.
For
this
reason,
turn
the
control
switch
for
the
strobe
lights
OFF
and
wait
for
at
least 10
minutes
to
elapse
before
disconnecting
the cables
at
the
power
supply
or
light
assemblies
and before
handling
or
disassembling
either
of
these
units
in
any
way.
Failure to
observe
these
precautions
may
result
in
physical
injury
from
electrical
shock.
