SECTION I INSTALLATION 7
1.0 DPU, SWITCH, DISPLAY CABLE INSTALLATION
1.0.1 DPU MOUNTING
The unit should not be mounted in the engine compartment, but
v installation and removal. NOTE: lf you have a'Fuel Level System'
you may want to calibrate it before mounting the DPU. (See section
on FUEL LEVEL SYSTEM OPERATION.)
1.0.2 DPU WIRING
All power, ground and transducer wires (except fuel level transducers
connect) to the DPU terminal blocks. See each respective
installation section for conneclions.
= DO NOT: connect J4-16 to the same aircraft circuit breaker as
J4-1 5.
- DO NOT: allow wire insulation or foreign objects into the
position being connected to.
- DO NOT: over tighten the set screw onto the wire. lnstead,
the wire needs to be securely held, but not crushed to the
point of separation. Test the wire for security after tightening.
The use of a 'Jewelers Screwdrive/ will provide enough
\--l torque for the job.
3 DO NOT: allow bare wires touch the metal case or adjacent
leads.
= DO NOT: bend the wires where they exit the terminal block
position, instead, form a radius away from the terminal block
position.
::) DO NOT: allow static electricity to contact any terminal.
Always discharge yourself to ground first !
DPU 'J4'TO POWER CONNECTIONS (Use 16 AWG wire)
All other DPU connections are described in each system installation
section.

SECTION I INSTAI,[,A'T'ION
1.0.3 INDICATOR MOUNTING & WIRING
The indicator is mounted to the panel from the back side. Four
mounting screws are provided for this purpose. Do not use longer
screws or damage to the instrument will result. The supplied screws
will accommodate panel thicknesses from 0.062 to 0.050 inches. lf a
panel thickness of other than this is required, then determine the
difference in thickness and procure new screw length accordingly.
Test your new screw lengths by finger tightening them into the panel
and indicator. The screws should tighten against the panel only and
should not 'bottom out' in the indicator. Be careful not to cross thread
the screws or the indicator bezel will be permanently damaged. The
indicator cut-out and mounting space requirement's information is
provided in 'SECTION 5 ILLUSTRATIONS'.
To wire indicators to DPU simply plug any display cable connector
into the back of the indicator observing the keying tab to notch.
1.0.4 DISPLAY CABLE FABRICATION
(P/N 401000s)
STEP 1: Carefully move the connectors into the positions required on
the flat. ribbon cable for your panel layout. They may face
either up or down. Look for the small embossed arrowhead on
the cable connectors that points to an edge of the cable.
MAKE SURE ALL CONNECTOR ARROWHEADS POINT TO
THE SAME EDGE OF THE CABLE AS THE INSTALLED DPU
CABLE CONNECTOR I
STEP 2: The connector is secured to the ribbon cable by closing it in
clean smooth jaws of a vise until ine sides 'snap over' into
position. Make sure the cable connector is SQUARE TO THE
CABLE before any closing takes place. Once installed,
connectors and cable cannot be re-used !
STEP 3: Once all connectors are installed, trim any excess cable
away by using a new SHARP pair of scissors. lnspect the cut
to insure that adjacent wires are not touching each other.
INSURE that once installed, the trimmed ends of the cable do not
touch anything.
50lr)002 REv FVM IIIIIII OWNERS MANUAL

SECTION I INSTALLATION
1.0.5 MODE SWITCH INST.
(P/N 3010023)
The mode selector switch assembly can be mounted anywhere within
reach of the indicator connector.
STEP 1: Once the switch hole has been located and drilled, remove
the paper backing and vinyl front covering from the switch
plate. The switch plate has an adhesive backing to aid in
placement of the plate. Press the plate into position.
STEP 2: Rotate the switch shaft as far counter-clockwise as it will
travel (as viewed facing the shaft). The switch comes with the
lock washer and nut loosely installed. When removing the nut,
DO NOT remove the silver ring underneath. lf you have
accidentally moved the silver ring, it should be placed back
onto the switch with the tab inserted into the hole between
switch position numbers '9' and '10'. This tab acts as a stop to
only allow 9 possible switch positions.
STEP 3: lnsert the switch assembly (switch, silver ring and lock
washer) through the back of the panel. Place the nut on the
switch and finger tighten. Place the knob over the shaft such
that one of the two set screws is perpendicular to the 'flat' on
the shaft. Tighten this set screw. Now rotate the entire switch
assembly until the slotted line on the knob is aligned with the
left lower white line on the switch plate.
STEP 4: lf necessary, carefully remove the knob without disturbing
the current switch assembly location. Now CAREFULLY
tighten the nut (too much force will break the switch) . lf
necessary, reinstall the knob as before and tighten both set
screws. Verify correct alignment with all switch plate positions.
Plug the switch assembly connector into the small connector
on the appropriate indicator.

1.1 TACHOMETER SYSTEM INSTALLATION
1.1 .1 TACH XDUCER INST.
(P/N 3010004 BENDIX, 3010005 SLICK)
The transducer is screwed into the 'magnet vent port' nearest the
magneto mounting flange, where the magneto attaches to engine. Do
not mistake the 'rotor vent port' nearest the spark plug harness
assembly for it.
lf possible, install xducer to the non impulse coupled magneto. See
engine manual for correct location.
Once properly identified, remove the existing vent plug and screw the
sensor in its place, then tighten.
lf you are connecting to an Electronic lgnition, only connect the
manufacturers 'tach signal output' to J4 -12 and install blocking diode
(such as 1 N914) in series with cathode (bar) going to ignition side.
*** CAUTION*** Always discharge yourself to ground before wiring,
