Coolant temperature is read through a temperature transmitter. An overtemperature switch provides automatic
shutdown in the event that coolant temperature exceeds 220 ± 3°F. The engine lube oil pressure is read through
a pressure transmitter. A low oil pressure switch provides automatic shutdown in the event that oil pressure falls
below 20 ± 2 psig. The day tank is equipped with a double float switch which controls the fuel solenoid valve and
provides automatic shutdown when only enough fuel remains for one minute of operation. The components of the
engine electrical system are connected electrically through the engine wiring harness.
(1) Refer to paragraph 3-4 and service the batteries.
Battery electrolyte contains sulfuric acid which can cause severe bums.
Handle batteries with care. If electrolyte should contact the skin or clothing,
rinse immediately with clean water.
(2) install batteries and connect as shown in Figure 4-2.
When installing battery cables, always connect ground (negative) cable last.
(3) install retainer and secure with washers and nuts.
(4) Apply an approved corrosion preventive compound to battery posts and cable terminals.
(a) Remove battery tray retaining screws and washers (Figure 4-2) and slide battery tray out
(b) Remove nuts, washers, and retainer (Figure 4-2).
(c) Remove battery cables.
When removing battery cables, always disconnect ground (negative) cable first.
(d) Remove batteries from battery tray.
(2) Installation. Refer to subparagraph a. above for installation instructions.
(1) Tests specific gravity of electrolyte in each battery cell with a hydrometer. Refer to Table4-3 for specif-
ic gravity temperature corrections. Refer to Table 4-4 for state of charge with specific gravity cor-
rected to 80°F.
Batteries generate hydrogen, a highly volatile gas, during charging. There
shall be no smoking or open frame in the vicinity. Failure to observe this
warning could result in an explosion, severe pereonal injury or death.
(2) Recharge or replace batteries as necessary.
