In the Field
The launcher/loader module (LLM)
can operate on battery power alone for
only 20 minutes. So operate the LLM
with the engine running at high idle as
much as possible. That’ll provide
enough juice to recharge the batteries
and run the LLM.
Check the batteries’ electrolyte level
daily. Operating with such a high load
requirement can dry out the batteries.
Every 6 months, you and your
mechanic need to pull all the
batteries and check the battery
box for corrosion.
If you spot any,
rub it off with a
wire brush and spot
paint any bare areas.
In the Motor Pool
Don’t let your MLRS sit idle for long
periods. Weekly, run the engine at high
idle for 30 minutes with the fire con-
trol panel in the ON position to charge
the batteries.
Check for corrosion and loose connectors
If new batteries have been installed,
don’t assume they’re fully charged.
Run the engine at high idle for 15–20
minutes with the fire control panel in
the ON position to charge them.
Gently tug at the battery post
connections to see if they are loose.
Get your mechanic to tighten loose
connections.
Check the gaskets that go around
the eight bolts that hold the battery
and electronics boxes together.
If they’re missing or in bad shape,
water can get in
both boxes and
cause corrosion
and electrical
problems. Report
gasket problems.
Then look for corrosion around the
battery terminals and clamps. Your me-
chanic can clean away corrosion with
a mixture of baking soda and water.
