Pay attention to cables.
If the cables that connect to the
rear of the launcher are loose or in
bad condition, you're going to have
power problems and firing faults.
Feel all the cable connectors to make
sure they're tightly screwed on.
Make sure none of the cables are
kinked—that could damage cable
wiring.
Look for cuts in the cables' cover-
ing. Cuts let water corrode the
cable's wiring. Cover small cuts with
electrical tape to seal out water. Cuts
larger than an inch need your repair-
man's attention. He may need to put
shrink tubing over them.
Keep cables connected as much as
possible. That keeps dirt and mois-
ture out of the connectors. If you do
have to disconnect cables, screw on
their protective caps. If the caps have
disappeared, tie a plastic bag over
the connector. Order new caps.
•
Remove the travel locks before raising the launcher.
Sounds simple, but every year some Patriot crew for-
gets. And that can bend the launcher platform, which is a
big league repair. Before you hit the button to raise the
launcher, visually check that both travel locks have been
removed. And make sure the locks have lanyards.
Otherwise, the locks will disappear.
•
Take it easy with circuit cards.
They're expensive and critical
to the launcher. Make sure the
power is completely turned off
before installing a circuit card.
Just flipping off the 28V switch is
not enough. Otherwise, the circuit
card can be zapped when you
plug it in.
Use the circuit card extractor to
remove and install circuit cards.
Using pliers can damage the card.
Make sure you're putting the card
in the right slot. If the card does-
n't slide in easily, you've probably
got the wrong slot. Forcing the
card can damage it and the slot.
