Engine Controls and Instruments
The engine control panel (fig. 2-9) is located on the
roadside of the semitrailer, above the piping assembly
(figs. 2-11 and 2-12). Control functions and gage readings
are explained in the following paragraphs.
a. Preheater Switch.
Connects battery voltage to glow
plugs in engine intake manifold to preheat the engine.
(Engine switch, item b, must be in RUN position.)
b. Engine Switch.
In RUN position, energizes engine
electrical system and fuel pumps to permit engine
operation. STOP position cuts off fuel supply and stops
the engine.
c. Indicator Light.
This should turn on when
Preheater Switch is turned to ON position. If light does
not come on, it indicates there is no current flow to the
manifold heaters and glow plugs.
