Remote Switch Harness Fabrication
1)
See Figure 21.
Figure 21 Remote Switch Harness Arrangement
2)
Fabricate a 5-wire harness long enough to reach from the ELT to the cockpit remote switch, allowing
enough slack to provide a drip loop at the ELT end and a service loop at the cockpit remote switch
end. See Figure 22 on page 50.
NOTE:
If an ELT/NAV Interface (453-
6500) is being installed with the ELT, refer to the “ELT/
NAV Interface Abbreviated Component Maintenance Manual” (570
-4602) for
additional wiring instructions.
a)
Strip approximately 0.15 in. (3 mm) of insulation from the ends of each of the five cable wires.
b)
Dress and tin the bare wires to prevent the strands from fraying during terminal crimping
operations.
3)
Three additional wires are required. See Figure 22 on page 50.
a)
Fabricate a ground wire long enough to reach from Pin 11 of the harness ELT receptacle to
aircraft ground.
NOTE:
This wire will be crimped in the same pin as the wire running from Pin 11 of the ELT
receptacle to the cockpit remote switch plug. Alternatively, the wires may be spliced
in a manner acceptable to the aircraft manufacturer, or as described in AC 43.13-1,
Paragraph 11-167.
b)
Fabricate ground wire long enough to reach from Pin 9 of the remote switch plug to aircraft
ground.
c)
Fabricate a power wire long enough to reach from the remote switch plug (Pin 1 or Pin 3) to the
selected aircraft power source.
d)
Prepare the wires as described in Steps (2)(a) and (2)(b).
