holes. Set the selector to ROCKET
for the A-B check and to CHARGE
for the B-C check.
If it’s
good,
connect
the W5
cable and
do the
same
checks.
If the
W5’s OK,
plug it
into the
safety
box. Lower
the launch rail and do the same
A-B and B-C tests on the safety
box cable. The M51 shouldn’t light
up on either test. Raise the rail
and do the two tests again. Now
the M51 should light up.
Lower the rail and plug the
safety box cable into the tub’s
charge box. Do the normal
continuity test.
If at any point a box or cable
flunks the test, you know
immediately what must be
replaced.

Dear Editor,
TM 9-1375-215-14&P says to
check the MICLIC’s continuity by
connecting the electrical
armament system control box to
the safety box and the safety box
to the charge box before testing
with the M51 blasting cap test
set. That will show a short, but
not its location.
Perfectly good
components are sometimes
replaced as a result.
We’ve found it more effective to
test each component individually
like this:
Make a shunt wire from a 2-in
piece of commo wire. Hook the
M51 to the control box. Connect
the shunt to the box’s A and B
holes to test ROCKET and to the
B and C holes for the CHARGE
test. If the M51 light lights up for
both tests, the box is good.
Next connect the W3 cable to
the control box. Do the same test
for the W3’s A and B, and B and C
oh, oh.
you have a
short
.
yeah,
but
where
?
TM 9-1375-215-13&P is replacing the -14&P and has an improved procedure,
but both procedures will work fine for troubleshooting. If you don’t have the new
TM, get your pubs clerk to order it.
