Wiring

SUBTASK 25-62-03-990-001

A.

General Considerations and Recommendations

CAUTION: IF GROUND OR OTHER CONNECTIONS ARE BROKEN OR OTHERWISE DAMAGED, THE ELT

IS STILL CAPABLE OF AUTOMATIC ACTIVATION; HOWEVER, THE COCKPIT REMOTE
SWITCH MAY BE INCAPABLE OF RESETTING THE ELT AND OPERATION MAY NOT BE
INDICATED ON THE REMOTE SWITCH LED.

CAUTION: INCORRECT TERMINATION OF THE WIRING IN THE CONNECTORS MAY DAMAGE THE

ELT, CAUSE TRANSMISSION ISSUES, OR RESULT IN A NON-FUNCTIONING REMOTE

SWITCH. VERIFY THE WIRING AGAINST THE WIRING DIAGRAM AND PERFORM A
CONTINUITY CHECK TO CONFIRM GOOD CONNECTIONS AND PROPER PIN LOCATIONS.

CAUTION: TO PREVENT INADVERTENT ELT ACTIVATION OR POSSIBLE COMPONENT DAMAGE, DO

NOT CONNECT THE HARNESS TO THE ELT OR COCKPIT REMOTE SWITCH PANEL UNTIL
ALL POWER AND GROUND WIRING CONNECTIONS ARE COMPLETED.

1)

The following wiring and grounding considerations and recommendations are applicable:
a)

Minimum 22 AWG wire size.

b)

Shielding is recommended to help prevent EMI and RF interference.

c)

Use high quality conductor meeting MIL-W-16878, M22759, M27500, or a commercial equivalent
acceptable for use in aircraft applications.

d)

Provide a “Drip Loop” in the remote switch harness connection to the ELT to divert moisture from

the connector. See TASK 25-62-03-990-805 on page 14 for a definition.

e)

Provide a “Service Loop” in the remote switch harness connection to the remote switch panel, such

that the assembly can be withdrawn from the panel far enough to easily disconnect the harness
plug. See TASK 25-62-03-990-805 on page 14 for a definition.

f)

ELT and remote switch panel grounds must be common to aircraft ground.

Remote Switch Panel Harness Fabrication and Installation

1)

In most cases, the aircraft has been pre-provisioned with wiring for connecting the ELT to the G737

control panel (remote switch panel assembly). Install a remote switch panel harness in accordance with
the following instructions ONLY if wiring has not been provided and/or spare wires are not available.
NOTE:

If spare wires are used, terminate the wires in accordance with Figure 20 Remote Switch
Panel Harness Wiring Diagram on page 53, and the procedures herein.

NOTE:

If an ELT/NAV Interface -B (453-6501) is being

installed with the ELT, refer to the “ELT/NAV

Interface -

B Description, Operation, Installation and Maintenance Manual” (570

-6501) for

additional wiring instructions.
