(5). Visually inspect wire harness for strain
at termination points, free movement of
shock-mounted or hinged equipment,
and proper slack for equipment instal­
lation and maintenance as follows:
(a). Harness slack shall be provided to
allow face-mounted instruments or
console control units to clear face of
instrument panel or structure by a
minimum of 1.5 in. (38 mm).
(b). When harness is terminated to a
connector, a minimum of 1.0 in. (25.4
mm)
of slack for one connector
replacement shall be provided.
(c). When harness is terminated to lugs,
allow a minimum length of slack
equal to 3
times the barrel length.
(d). Harness slack shall not exceed
0.5 in. (12.7 mm) from imaginary
centerline between clamps except
when providing for connector replace­
ment, drip loops, excess wire and
similar conditions.
(e). Adjust harness routing as necessary
to obtain proper slack at termination
points.
(6). Visually inspect for absence of drip
loops where required using the follow­
ing criteria:
(a). Apply drip loops to wiring where
moisture accumulation on wire can
drip down to termination and cause
corrosion.
(b). Downward attachment of terminal
lugs should be used in conjunction
with drip loops when possible.
(c). Observe minimum bend radius of
wires.
(7). Inspect wire harness for contamination
by fluids and dirt particles.
(a). If contamination is found, decontami­
nate harness (Ref. Cleaning and
Protection Practices).
