B. Remote Switch Harness Fabrication
(1) See Figure 20 Remote Switch Harness Arrangement.
Figure 20 Remote Switch Harness Arrangement
(2) Fabricate a 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. Refer to the appropriate wiring diagram.
(a) Strip approximately 0.15 in. (3 mm) of insulation from the remote switch end of each of
the harness cable wires.
(b) Dress and tin the bare wires to prevent the strands from fraying during terminal
crimping operations.
(3) Fabricate ground wires as required, based on the wiring diagram appropriate for the
installation.
(4) Fabricate a power wire long enough to reach from the remote switch plug (Pin 1 or Pin 3) to
the selected aircraft power source.
(5) Prepare the wires fabricated in Steps (3) and (4), as described in Steps (2)(a) and (2)(b).
(6) Fabricate two wires, one of sufficient length to reach from the ELT D-Sub connector plug to
the buzzer and the other from the buzzer to ground.
NOTE
: These wires provide power and ground for the buzzer. Use appropriate means of
identification for the wires, such that the wires can be readily identified.
