7. Check the engine speed. The engine speed
should be 1890 ± 10 RPM with No Load and
the Speed Solenoid On.
a. If necessary, loosen the jam nut on the
high speed adjustment screw.
b. Adjust high speed adjustment screw to
change engine RPM.
c. Tighten the jam nut on the high speed
adjustment screw when the speed is
correct.
8. Exit the System Setup submenu by pressing
the

key as necessary to return to the
Main Menu.
Integral Fuel Solenoid
The fuel solenoid contains 2 coils: the pull-in coil,
and the hold-in coil. The pull-in coil draws
approximately 35 to 45 amperes at 12 volts. The
hold-in coil draws approximately 1 ampere at 12
volts. The pull-in coil must be energized to move
the injection pump governor linkage to the fuel
“ON” position. Once the governor linkage is in
the fuel “ON” position, the hold-in coil will keep
the linkage in the fuel on position until the 8D
circuit is de-energized. The pull-in coil must be
de-energized after a few seconds to keep it from
being damaged.
DIagnosing the Integral Fuel
Solenoid System
NOTE: The fuel solenoid pull-in coil may
require 35 to 45 amperes to pull the solenoid
plunger in. The unit’s battery must be in good
condition. If the battery has enough power to
crank the engine over, it has enough power to
energize the fuel solenoid pull-in coil.
