A Plug for Plug ID
Dear Editor,
The troubleshooting procedures for the Paladin’s charging system
require removing the cannon plugs for the fuel pump generator system
relay and the blower motor relay.
Both cannon plugs look the same, so it’s easy to accidentally mix up
the plugs when reconnecting them to the relays. If you do that, the
system won’t charge at all and you’ve just compounded your original
charging problem.
We’ve stopped the
mixup by painting a
small white mark on one
cannon plug and relay.
The next time both have
to be unplugged, it’s
obvious which plug goes
to which relay.

A
leaky seal on the Paladin’s cupola cover
means more than a wet crew, mechanics.
If you don’t install the seal correctly, it
also lets water drip directly onto the display
unit (DU), NSN 7025-01-307-5519. When
the DU shorts out, you have to replace it to
the tune of more than $31,000!
Keep the DU—and the
Paladin crew—dry by installing
the new seal like this:
1.
Remove and discard the old
cover seal.
2.
Scrape away any dirt or old
adhesive from the cover seal
groove. Make sure you get it
all. If any is left, the new seal
may leak.
3.
Apply adhesive, NSN 8040-
00-152-0063, to a new cover
seal, NSN 5330-01-453-1007,
and press the seal into the
groove.
Report
any leaks
as soon as
you notice
them.
Crewmen, do your
part by keeping dirt
and sand brushed
away from the seal
groove before they
can cause damage.
how ‘bout
replacing
that leaky
seal in my
paladin’s
cupola?
I gotta
go change
MY clothes!
I’m soaked!
yeah!
And I
could use a
new display
unit while
you’re at it!
I don’t get it! I went
through the trouble-
shooting procedures
and now it won’t
charge at all!?
maybe you mixed
up the plugs for
the fuel pump
generator system
and blower
motor relays!

You’ve plugged up that potential
