eep your Patriot’s AN/MPQ-
53 radar radiating good health by
being careful and doing PM.
Keep your feet away from the
identification friend or foe (IFF)
system elements and the main
array elements.
Damage to these
elements can cause the radar to fail.
Pay attention to vents.
If the radar
doesn’t get enough cooling air, it over-
heats and produces lots of test faults. So,
before powering up the radar, make sure
all eight vents are open. Monthly, eye-
ball all the vent screens for dirt. Check
the screens more often in dusty areas. If
you can’t vacuum the screens clean, get
‘em replaced.
No power? Check the J5 control
cable on the electric power plant
(EPP) III.
If the cable is cross-thread-
ed, no power gets to the radar. A quick
check of the cable can save trou-
bleshooting. Of course, if the cable
covering is torn or cracked, get the
cable replaced
Careful with the J1, J2, J3 and J6
cables.
If you screw the cables on or off
one-handed, you rip their wiring and
ruin expensive cables. Support each
cable with one hand while you twist the
cable connector sleeve with the other
hand. Don’t let the cable turn—only the
connector sleeve should turn.
Keep feet away
from elements
Make sure all eight vents
are open. Vacuum dirty ones
Support cable while
turning connector sleeve
No power?
Check J5 at EPP
Patriot Missile System.
