It's what's inside that counts. That's the story on the turret-power rElay±
control boxes for ²he M60-seies tanks and the M728 combat engineer vehicle.
These boxes look alike on· the outside even though they have different stock
numbers and different internal wiring. Use the wrong one and your tank will be
low or high on electrical power and blow its relAys or other components
³
often´
Some control boxes are interchangeable while others_cµn be used with only
one kind of track.

take care of you if you
know what kind of box you have. If you
don't know, get your turret mechanic
to open up the box. He can tell you
what kind it is by the internal wiring.
This situation will get better
because all new production boxes will
have part numbers on them. ¶lso, as
an interim measure, your friendly
DSU can put part numbers on the
outside of boxes they issue´ ¶uthority
for this is on page 4¸42 of TB 43-00¹1º
36º1 (¶pr 75).
For now, when you turn in one of
these» boxes for DX, put the right
NSN on the exchange tag (D¶ Form
2402).
