A. Remote Switch Control Panel Wiring Fabrication
(1) In most cases, Boeing aircraft have been provisioned with wiring for connecting the ELT to the
control panel. Install a remote switch control panel harness in accordance with the following
instructions ONLY if wiring has not been provided and/or spare wires are not available.
NOTE: Terminate the wiring in accordance with "Figure 34. Remote Switch Control Panel
Wiring Diagram (130-4005 Modified Buzzer)”, on page 96, and the procedures
herein.
(2) Fabricate a 4-wire harness long enough to reach from the ELT to the remote switch control
panel, allowing enough slack to provide a drip loop at the ELT end and a service loop at the
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 34. Remote Switch Control
Panel Wiring Diagram (130-4005 Modified Buzzer)”, on page 96.
(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
34. Remote Switch Control Panel Wiring Diagram (130-4005 Modified Buzzer)”, on page 96,
and the specific aircraft wiring diagrams to determine appropriate connection points.
(a) Pin 3 to the selected +28V aircraft power source.
(b) Pin 4 to the selected +28V/+16V aircraft power source.
(c) Pin 6 to the Master Caution +17V 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).
