Next, check for corrosion around the battery terminals and clamps. Your mechan-
ic can clean away corrosion with a mixture of baking soda and water.
T
he MLRS’ launcher module (LM) is only as effective as the batteries and charging
systems onboard. If the LM batteries aren’t in good shape before you go to the field,
or aren’t given a chance to recover after use, you’ll come up short on power—maybe
at a critical time.
PMCS
Before you go to the field, check the battery electrolyte level in each of the bat-
tery cells. If it’s low, get your mechanic to add distilled water. Then run the engine
at high idle—1,200 to 1,400 rpm—for 15-20 minutes with the LAUNCHER
INTERCONNECT switch turned on to recharge the batteries.
Gently tug at the battery post
connections to see if they are
loose. Get your mechanic to
tighten loose ones.
Just because new batteries
have been installed is no reason
to assume they’re fully charged.
Run the engine at high idle for
15-20
minutes
with
the
LAUNCHER INTERCONNECT
switch on to charge ‘em.
Eyeball the gaskets that go
under the eight bolts that hold the
battery and electronics boxes
together. If the gaskets are miss-
ing or damaged, water gets into
the boxes and causes corrosion
and electrical problems.
Check electrolyte
level in each cell
Charge at high idle with LAUNCHER
INTERCONNECT switch to ON
Check clamps
for looseness
Look for missing or damaged
gaskets under bolts
yikes!
Without
LM power,
I can’t
fire back!
