MLRS mechanics, connector adapt-
ers on W19 and W20 cables are the
best investment your unit can make.
With the adapters screwed on the
cables’ connectors, the cable connec-
tor pins can’t be broken when the
cables are hooked up. That means ex-
pensive cables don’t have to be
replaced.
Cost savings: The W19 cable costs
more than $700. Its adapter, NSN
5935-01-155-9847, costs $130. The
W20 cable costs more than $900. Its
adapter, NSN 5935-01-238-5896, costs
$130.
Most MLRS units are missing many
of the W19 and W20 adapters. Check
your MLRSs and order replacements
for missing adapters. And make sure
MLRS . . .
your unit leaves them on. Check that
adapters are still on before and
after field exercises. Replace missing
adapters.
One other adapter tip: Because the
W19 and W20 cables are hooked up
and unhooked repeatedly during a mis-
sion, the adapters can get dirty. That
leads to UMBILICAL CONNECTOR
NOT CONNECTED or SNVT (short/
no-voltage tester) faults. Repairmen
often think it’s a cable problem and
replace the cables, which is an expen-
sive fix.
When you get those faults, take
off the adapters and clean them with
electrical contact cleaner, NSN 6850-
01-371-8048. That usually erases
faults. Circuit board contact cleaner
works, too.
