Fuel Solenoid (Greensmaster 3400 machines)
The fuel solenoid used on Greensmaster 3400 ma-
chines must be energized for the diesel engine to run.
The fuel solenoid is mounted to the injection pump on
the engine (Fig. 66). The Toro Electronic Controller
(TEC) energizes the fuel solenoid when the ignition
switch is in either the RUN or START position.
Thefuelsolenoidincludestwo(2)coilsforoperation:the
pull c oil and the hold coil. When the ignition switch is
turned to START, the fuelsolenoid pull coil is energized
and the solenoid plunger retracts. Once the plunger is
retracted,theholdcoilwillkeepitretractedforcontinued
engine operation. When the solenoid is de--energized,
the plungerextends to shutoff fuelsupply to theengine
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 notfunctionandthe enginewill
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.
