4-5. NIGHT SENSOR ASSEMBLY (NSA) REPAIR (cont)
CAUTION
• Flexible harness is very fragile. Be very
careful not to cut it, make sharp bends, or
chafe it against the cooler/Dewar or the night
sensor assembly chassis.
• Do not try to bend flexible printed harness
unless heated and pliable. Do not overheat.
Too much heat will damage printed cable.
NOTE
• A heat source of approximately 200°F is
best to make harness soft and bend easily.
Holding heat gun approximately 5 inches
from the heat point will usually apply about
200°F.
• The following step requires two people
working together. Read and understand the
step before starting.
ab. Install flexible harness connectors and
preamplifier motherboard (36) in night
sensor assembly.
