Section VIII. MAINTENANCE OF BATTERIES AND RELATED ITEMS
4-13. GENERAL. This section contains information on
the batteries, battery tray, and battery cables of the
engine generator set. Four 12-volt, 200 ampere hour,
20-hour rate, lead-acid type batteries in series-parallel
connection supply 24V DC for starting the engine in the
a. Replacement. (See Figure 4-9)
Remove negative battery cables first,
and insulate and secure.
Disconnect all negative cables first then
positive, and jumper cables from the
batteries. Disconnect the battery leads
from the starter motor (see figure 4-44).
Reconnect positive cables (4 and 3, figure
4-9) numbered P140XX and P140H to the
positive post of batteries BR3 and BT2.
Reconnect two jumpers (1) between the
negative and positive post of batteries
BT1 and BT2; and BT3 and BT4.
Reconnect negative cables (5 and 2)
numbered P55XX and P55YY to the
negative post of batteries BT1 and BT4
and to ground post P2 on engine block.

a. Cable Construction. There are six separate
battery cables (five different lengths and terminations)
constructed as follows:
Wire, electrical, 4/0 (P/N MIL-C-5756)
Terminal lug (P/N MS25036-141)
Battery terminal lug (P/N 76-11294-01 and 76-11294-
Insulation, sleeving 1-1/2 in. (38. 1 mm) ID, red and
Cable P/N 76-11424-01, see figure 4-10,
Cut wire to 81 inches (206 cm) and
strip insulation from both ends.
Strip 0. 62 inch (15. 7 mm) at
terminal lug end, and 0. 75 inch (19
mm) at battery terminal lug end.
Attach battery terminal lugs on ends
of wire as shown. Orient the lugs as
shown, then crimp the terminals
Push sleeving up to terminals and
apply heat of 400°F (204°C) for 3 to
Cables 76-11424-02, 76-11422-01, and
76-11422-02 can be constructed the
same way, only length of wire differs.
Cable P/N 76-11423 is fabricated similar
to other cables, except that the wire has
battery terminal lugs at both ends, see
figure 4-10, detail B.
