1.6.1
ELECTRICAL
SYSTEM
INST.
Follow the instructions
below
to
install
the
volt
and amp
functions.
1.6.2 VOLTAGE
SENSE
WIRE
INST.
The sense wire can
be
connected
directly
to the
main
bus,
the
avionics bus,
or
any other
point
for
voltage
measurement,
as
long
as
the
voltage
does
not exceed
+36
VDC.
1.6.3 AMP TRANSDUCER
INST.
(P/N
3010022)
The amp system
functions
as an'alternator
load
meter'displaying
current flow FROM the alternator
TO the
aircraft electrical system
allowing
you
to see
if
a
load
(such
as
pitot
heat) is really
drawing
current.when
turned on.
The transducer
is
mounted
in
the
cabin area.
Route the wire connecting
the
alternator
output
(usually
marked
'BAT')
through the
transducer
so that
it
EXITS
ON
THE
TRANSDUCERS
BLACK PLASTIC
SIDE
then
continues
ultimately to
the breaker
/ main
bus. lf
properly
installed,
the AMPS
readout will
increase as more
electrical loads
are
turned on
and the alternator
is
active. Shielded
alternator
wire is OK.
