ELT Troubleshooting Guidelines

Table 7 provides ELT troubleshooting guidelines for installation and operational issues.

SYMPTOM

PROBABLE CAUSE

POSSIBLE SOLUTION

Remote switch LED always on

(steady)

Improper wiring

Verify wiring

Short circuit

Check for frayed insulation

Verify LIGHT_ON wire. Check

continuity between pin 2 and pin 9

on remote switch harness

connector with ELT disconnected

from harness. If short to ground is

present, correct wiring short and

reinstall remote switch.

Remote Switch Faulty

Replace Remote Switch

ELT Faulty

Disconnect remote switch from

harness. Check continuity

between pin 2 and pin 9 on

remote switch harness connector

with ELT connected to harness. If

short to ground is present with

ELT deactivated, return ELT to an

Artex authorized repair facility.

ELT will not turn off

Battery too low to support 406

burst and causes circuit to reset

Remove battery pack to disable

ELT and replace battery pack

Turn off ELT using local switch - If ELT turns off:

Defective remote switch harness

reset circuit wiring

Check wiring continuity and repair

as necessary

Defective remote switch

Replace remote switch

If ELT does not turn off using local switch:

ELT defective

Remove battery pack to disable

ELT and return ELT to factory for

servicing
