6. If the wire is too short to make a secure connection, use the existing wire to pull a replacement wire

through the conduit from the junction box at the light fixture.

7. Inspect the light switch. If the switch is damaged, go to Step 9.

8. Turn the switch on. Using the multimeter, check continuity between the switch input and output

terminals. If you do not detect continuity, go to Step 9. If there is continuity, change the wires as

described in Step 3.

9. Remove the damaged switch assembly. Loosen the wire terminal screws on the switch, tag and

disconnect the wires from the terminals.

10. Connect the wire ends to the replacement switch, ensuring that each tagged wire is connected to the

proper terminal. Make sure the terminal screws are secure.

11. Insert the new switch in the enclosure, making sure no wires are pinched. Install the retaining screws

removed in Step 3.

12. Replace the cover plate and screws removed in Step 2. Make sure the gasket is in good condition

and properly located.

13. If no gasket is available or if it is not serviceable, caulk the perimeter of the plate with silicone sealant

to provide a watertight seal.

14. Connect a 110 VAC 60 Hz power supply to the power input connector and test the operation of the IC

electrical system as described in Work Package 0018 00.
