Electrical System
Fuel Solenoid
The fuel solenoid used on Greensmaster 3250--D ma-
chines must be energized for the diesel engine to run.
The fuel solenoid is mounted to the injection pump on
the engine (Fig. 36). The fuel solenoid is energized
when the ignition switch is in either the RUN or START
position.
Thefuelsolenoidincludestwo(2)coilsforoperation:the
pull coil and the hold coil. When the ignition switch is
turned to START, the fuel solenoid pull coil is energized
and the solenoid plunger retracts. Once the plunger is
retracted,theholdcoilwillkeepitretractedforcontinued
engine operation. When the solenoid is de--energized,
the plunger extends to shut offfuelsupply to the engine
causing the engine to stop running.
NOTE: A fusible link in the machine wire harness pro-
tects the fuel solenoid pull coil circuit. If this link should
fail,thefuelsolenoidwill notfunctionandtheenginewill
not run. Refer to electrical drawings in Chapter 10 --
Foldout Drawings when troubleshooting the fuel sole-
noid.
NOTE: See Kubota Workshop Manual, D iesel Engine,
SM--E3B Series for information regarding fuel solenoid
testing procedure.
