C.
Buzzer Wiring Fabrication
1)
Fabricate the following wires, which correspond with the wires on the buzzer:
NOTE:
Use appropriately coded wires, such that the wires can be identified and terminated at the
appropriate locations.
a)
YELLOW wire to harness ELT receptacle.
b)
BLACK wire to aircraft ground.
c)
RED wire to +28VDC aircraft battery power source.
d)
BLUE wire to Pin 8 of the remote switch panel connector.
e)
Strip approximately 0.15 in. (3 mm) of insulation from the ends of each of the harness wires.
f)
Dress and tin the bare wires to prevent the strands from fraying during terminal crimping
operations.
2)
Splice the fabricated wires to the buzzer wires in a manner acceptable to the aircraft manufacturer, or
as described in AC 43.13-1, Paragraph 11-167, as applicable.
3)
Support the wiring 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 instru
ctions or as
described in AC 43.13-1, Chapter 11, § 9 through 12, as applicable.

D.
ELT 12-Pin Receptacle Wiring Fabrication and Installation
1)
Fabricate a ground wire long enough to reach from 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 panel, ONLY if a ground wire is connected between
the ELT and the remote switch panel. 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,
as applicable.
2)
Feed the harness wires on the ELT end through the mounting frame cap assembly (452-5052). See
Figure 21 Remote Switch Panel Harness Wiring at ELT End on page 56.
NOTE:
Prior to installing the 12-pin ELT receptacle onto the harness, the wires connecting to the
ELT must be routed through the rectangular hole in the ELT mounting frame cap. The cap
retains the receptacle when installed and the receptacle will not fit through the mounting
cap harness entrance.
3)
Feed the buzzer wire (YELLOW) on the ELT end through the mounting frame cap.
4)
Fabricate a short jumper, approximately 1.5 in. (38 mm) long, using minimum 22 AWG wire.
a)
Strip approximately 0.15 in. (3.3 mm) of insulation from both ends of each of the wire.
b)
Dress and tin the bare wire ends to prevent the strands from fraying during terminal crimping
operations.
