GENERAL

This section outlines the procedures for removing and reinstalling the IC interior light assembly. Before

beginning this procedure, confirm that the light bulb is operational (see Work Package 0010 00, item 4).

The light assembly should only be replaced by an identical assembly or an approved substitute

(maximum 100 W).

REPAIR

1. Disconnect the IC power supply cable from the IC power entry connector.

2. Remove the cage, lens and light bulb from the light fixture as outlined in WP 0017 00.

3. Remove four screws from the light fixture base to separate the fixture from the junction box. Support

the fixture and remove the wire nuts. Retain gasket.

4. Examine the wire connections. Ensure the connections are secure.

5. Twist the loose ends, and secure the connection with a wire nut. Restore power to the electrical

system and test the fixture.

a. If the light works, disconnect power and reinstall the fixture, lamp, lens and cage. If the gasket is

serviceable, reuse it. If the gasket is not serviceable, replace it with a new gasket.

b. If the light does not work, disconnect the power supply from the system and replace the light

fixture.
