Since two power sources are connected to the fuel gage sksttem, a blEI::ng
diode (16) is required in each power source circuit. One d io& prevcn!;

Another diode prevents opration of the panel lights by tllc engine-gene-
erator circuit when the engine is running. To check fue I qucntity when
e ng irie is stopped, use switch (3) to turn ON punel lights.
(h) Cold wealher starting aid control
The push--pull control (12) contro!s operation of a cold weather starting cid
(4, Fig. 3). The starting aid consists of a group of items designed to' inject
a highly volatile fluid into the engine air intake system to ass!st igniticn
of fuel when air temperature is too low for the heat of comprezsian to
ignite a normal fuel mixture. The starting aid cons&& of a cylindrical,
fluid container and a valve (see l-3, Fig. 4) which are mount,zd on the
iifting yoke. The valve is opzrated by the control (12, Fig. 11). PuHing
the control outward allows fluid to flow into the valve.
Pushing the '
control IN forces fluid through a small tube end an atomizing nozzle into
the inlet manifoid. The addition of atomized, highly volutile fuel into
the inlet air assists in igniting the diesel fuel mixture.
(k) Engine stop control
.
The engine is normally stopped by use of the mechanical stop control (14)
which is a push-pull control cable connected to the engine fuel rack
lever.
Pulling the control outward places the rack in "no-fuel" pr~ition
to stop the engine.
(3) Air cleaner indicator
The air cleaner indicator (13) is mounted on the engine control panel fcr easy
viewing. Ifs function was explained in Para. 7, C , (3) (see Fig. 6).
