Dear Editor,
The battery box for the Avenger takes a beating from corrosion.
Battery acid leaks onto the bottom of the box and starts industrial
strength corrosion. Next thing you know, the box bottom has rusted
out and you need a new box.
We stopped the corrosion
with spray-on rubber. Remove
the batteries and clean off
any corrosion or dirt. Then
give the bottom of the box a
coating of rubber. You can
get the spray-on rubber in the
hardware section of most dis-
count stores. Wait till the
rubber dries and look for
uneven areas. Fill them in. You
want the coating as even and
flat as possible. After the
coating completely dries for
24 hours, reinstall the bat-
teries. The rubber will keep the
battery acid from reaching the
box's metal bottom.

Avenger Missile System…
Beat Battery Box Corrosion
(Editor's note:
Thanks for
bouncing your rubber idea off
us. It should save battery boxes.)
IFF
The nut for the J4 connector on the IFF interconnector box often works loose and
comes off. Then the connector can actually be pushed inside the box when you plug
in its cable. Sometimes the only way to fix it is to replace the whole box at a cost of
more than $1,000.
To keep the nut tight,
you have two choices:
tighten the nut every
week during PMCS or
lock-wire it tight to one
of the screws on the
front of the box. The nut
has a slot to run the wire
through and your armor-
er has lock-wire pliers.
Remove
batteries…
…and give
bottom of
battery box
a rubber
coating
Lock wire nut to
screw on front
you get all
cruddy
and
rusty
and who
wants to sit in that?
hold on boys, I
got the answer
for
both
of you!
yeah, well,
you leak out
acid and
gunk!
next time I
bet you’ll
remember
where to step
on my seat!
