2)
Fabricate a 4-wire harness long enough to reach from the ELT to the cockpit remote switch panel,
allowing enough slack to provide a drip loop at the ELT end and a service loop at the cockpit remote
switch panel end.
NOTE:
A 5 or 6-wire harness may be necessary if a ground wire is connected between ELT Pin 11
and remote switch panel Pin 9; and/or ELT Pin 2 must be connected to remote switch panel
Pin 8 if a horn is not installed. See Figure 20 Remote Switch Panel Harness Wiring Diagram
on page 53.
a)
Strip approximately 0.15 in. (3 mm) of insulation from the ends of each of the harness wires.
b)
Dress and tin the bare wires to prevent the strands from fraying during terminal crimping
operations.
3)
Fabricate the additional wires needed to connect the remote switch panel; referring to Figure 20 Remote
Switch Panel Harness Wiring Diagram on page 53, and the aircraft wiring diagrams to determine
appropriate connection points.
a)
Pin 3 to the se28V aircraft power source.
b)
Pin 4 to the se28V/+16V aircraft power source.
c)
Pin 6 to the Master C17V circuit.
d)
Pin 8 to the BLUE wire on the buzzer (i.e., horn).
e)
Pin 9 to aircraft ground.
f)
Pin 10 to the Master Caution Pulse circuit.
g)
Pin 11 to the Master Caution Steady State circuit.
h)
Pin 12 to the Master Lighting Test circuit.
i)
Pin 13 to the 5VAC Lighting circuit.
j)
Pin 14 to aircraft ground.
k)
Prepare the wires as described in Steps (2)(a) and (2)(b).
4)
Terminate the remote switch panel end of all wires in an MS24266R16B24S7 connector in accordance
with the aircraft manufacturer’s written instructions or AC43.13
-1, as applicable. See Figure 20 Remote
Switch Panel Harness Wiring Diagram on page 53.
NOTE:
Identify the wires and connector pin relationships, such that the wiring can be terminated
at the appropriate locations.
5)
Install the remote switch panel harness as follows:
a)
Bundle the wiring into a complete harness, with breakouts as appropriate, such that the wiring can
be properly
supported and attached to the airframe. Refer to the aircraft manufacturer’s written
instructions or AC 43.13-1, Chapter 11, § 9 through 12, as applicable.
b)
Route the wire bundle through the airframe.
c)
Support the wire bundle by clamping or other suitable means, such that the wiring is properly
supported and protected from chaffing and strain. Refer to the aircraft manufacturer’s written
instructions or as described in AC 43.13-1, Chapter 11, § 9 through 12, as applicable.
6)
Terminate the aircraft side of the wires fabricated in Step (3) at the appropriate connection points in
accordance with the aircraft manufacturer’s written instructions or AC 43.13
-1, as applicable. See Figure
20 Remote Switch Panel Harness Wiring Diagram on page 53 and aircraft wiring diagrams.
7)
Refer to SUBTASK 25-62-03-450-003 for wire termination instructions at the ELT end of the remote
switch panel harness.
