The batteries are charged by the battery charging
alternator that is belt driven by the engine. Generator set
control system power is also supplied by the battery charging
alternator. The BATTERY CHARGE ammeter indicates the
charge/discharge rate of the batteries, from -10 AMPS to +20
AMPS, in 5 AMPS increments. Normal operating indication
depends on the state of charge in the batteries. A low charge,
such as exists immediately after engine starting. will cause a
high reading (needle moves toward CHARGE area). When the
charge in the batteries has been restored, the indicator moves
near zero, 0.
1-12 FUEL SYSTEM.
The Fuel System (FIGURE 1-4), consists of piping,
fuel tank. fuel filter, electrically driven transfer pump, fuel
filter/water separator, four injection pumps and four injectors,
one for each cylinder. Fuel is drawn from the fuel tank by the
transfer pump when the MASTER SWITCH is in the PRIME
&RUN position. After reaching the transfer pump, fuel passes
through a fuel falter/water separator where water and small
impurities are removed. The fuel then goes to the injection
pumps where it is pressurized and pushed into the injectors.
Through the injectors fuel enters the diesel engine combustion
chamber, where it is mixed with air and ignited. The fuel that
is not used is returned to the fuel tank via an excess fuel return
line.

The Auxiliary Fuel System consists of an external fuel
pump and transfers fuel from the external fuel supply to the
