This procedure contains information and instructions to keep the MBU System in good working order by
inspecting and replacing the NATO Adapter Cable assembly.
Remove the outer cap (1) of the large power connector (2) and inspect the interior surfaces for any dirt,
damage, or corrosion that would prevent a good electrical connection. Inspect the connection point (3)
between the large power connector (2) and the cable (4) for any cracks, separations, or exposed wires.
Inspect the length of the cable jacket (5) for any cracks, cuts, or other damage that would expose the
inner wires. Inspect the small power connector (6) for any cracks, dents, or damage to the outer collar
that would prevent a proper and secure electrical connection. Inspect the interior surfaces of the
connector (6) for dirt or damage to the internal contacts. Ensure that the outer cable jacket (7) is securely
attached to the connector and that there are no exposed wires.
To replace the NATO Adapter Cable power cable, or the main power connector head (2) remove the 6
screws that secure the back cover of the main connector head (2) and remove the protective cap (1).
Remove the two hex head bolts (9) that secure the power cable (4) to the main power connector head (2)
and remove the cable assembly.
Install a new power cable or new main connector head (2) making sure to place the power cable strain
relief (3) into the slot on the main power connector head.
Place the power cable terminals in position by aligning the (+) positive lead of the cable with the (+)
terminal (10) on the main connector head (2) and install the two hex head bolts (9).
Place the back cover of the main connector head (2) into position. Place a new cap or the cap removed
earlier into position over the top screw hole (11) and secure the six cover screws (8).
