Dear Editor,
Through hard experience, we’ve come up with a couple of tips that will
help other Patrioteers operate the engagement control station (ECS) and
information control center (ICC).
o
On the A51 byte indicator panel,
the BASKET 2 POWER indicators
take a 5-volt lamp, while all the other
indicators take 28-volt lamps. So
you can’t swap lamps. If you do, you’ll
either blow the lamp or it won’t work.
Be careful to keep the replacement
5-volt lamps separate from the
28-volt ones. The base of the lamp
shows its voltage.
o
On the A64 generator control
panel, most crews assume that when
the red covers are down the three
switches are in the ON position. But
that’s not necessarily true. The
covers just keep the switches from
being bumped ON or OFF. The
switches can be OFF even if the
covers are down. If you’re having
power problems, check the three switches.
You could save lots of troubleshooting time.

!
here are
a couple of
patriot
tips
.
pm is still
a
revolutionary
idea
!
☛
☛
☛
If the kingpin has lots of wear, use a
micrometer or calipers to see if it is
out-of-round. If you don’t have these
tools, your support probably will.
Measure at the 12–6 and 3–9 o’clock
positions on the kingpin. A variance
of
1
/
16
inch or more over 25 percent
of the kingpin means it needs to be
replaced.
f the M860A1 trailer kingpin’s not
strong enough, it snaps off. When that
happens, the Patriot’s launcher or ra-
dar or whatever component is being
pulled stops right there. One Patriot
unit had several break in just a few
months.
Use these checks to catch weak
kingpins:
Completely wipe off all grease from
the kingpin and then clean it with dry
cleaning solvent. Grease hides prob-
lems.
Look for cracks, gouges, and chips.
Any cracks in the kingpin make it
NMC, as do any nicks, chips or gouges
deeper than
1
/
8
inch.

condition of a kingpin, report it. Do
these checks after every mission.
