Step 7. Check continuity in brown wire assembly between ground terminal at blackout light
and connector inside condulet at rear dam.
If there is continuity, brown wire assembly is O.K. Go to step 8.
If there is no continuity, check for loose or corroded mounting hardware where
brown wire assembly is grounded at blackout light (see paragraph 4-19).
Check for a loose or damaged ground terminal at blackout light end of brown
wire. If mounting hardware at blackout light is loose, tighten. If mounting
hardware is corroded or otherwise damaged, replace (see paragraph 4-19).
Repair or replace brown wire assembly as required (see paragraph 4-29). If
malfunction still exists, go to step 8.

White receptacle wire connects pin #1 of receptacle to brown wire assembly
inside condulet. Black receptacle wire connects pin #2 of receptacle to blue
wire assembly inside condulet.
Step 8. Check for continuity and a short in white and black receptacle wires inside condulet
at rear dam.
If both white and black receptacle wires have continuity, receptacle with wires
is O.K. Go to step 9.
If there is no continuity in either or both wires, or if a wire is shorted, replace
receptacle with wires (see paragraph 4-22). If malfunction still exists, go to
step 9.
