System Descriptions

ENGINE CONTROL SYSTEM (cont.)

Fuel Control Valve. The Fuel Control Valve (6/18) is mounted

on the Fuel Injection Pump. It is normally de-energized. In the

de-energized position, the high pressure output from the Injec-

tion Pump is bypassed into the fuel return line. The injector does

not receive fuel.

Off/Run/Start Switch.

+12 volts is taken from the

starter post, through the

wiring harness (red wire),

and applied to the terminals

of the Off/Run/Start switch

located on the control panel.

Run Position. When the

Off/Run/Start switch is

moved to the Run position,

+12 volts is applied back

through the harness (green

wire) to one side of the

water temperature switch.

This switch is normally

closed, so the +12 volts will

pass through the switch to

the exhaust temperature

switch, and also through the

harness (brown wire) to the

water lamp. The water lamp

will illuminate because the

engine coolant temperature

is below 185 degrees F.

Since the exhaust tempera-

ture switch is also closed,

the +12 volts goes to the oil

pressure switch, and also through the harness (orange wire) to

the exhaust lamp. The exhaust lamp will illuminate because the

exhaust temperature is also below 185 degrees F. The oil pres-

sure switch is normally open, so the +12 volts will stop at this

point with the two lamps illuminated.
