Engine Run Solenoid
The engine run solenoid used on Workman MDX--D
vehicles must be energized for the diesel engine to run.
The run solenoidismounted totheinjectionpumponthe
engine (Fig. 23).The runsolenoid isenergized when the
ignition switch is in either the ON o r START position.
The engine run solenoidincludes two (2) coilsfor opera-
tion: t he 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, thehold coil will keep it retracted for
continued engine operation. When the solenoid is de--
energized, the plunger extends to shut off fuel supply to
theenginecausingtheenginetostoprunning.
NOTE: Afusiblelink inthe enginewire harnessprotects
the engine run solenoid pull coil circuit. If this link should
fail, the run solenoid will not function and t he engine will
not run. Refer to electrical drawings in Chapter 7 -- Elec-
trical Drawings when troubleshooting the run solenoid.
NOTE: See Kubota Workshop Manual, Diesel Engine,
SM--E3B Series for information regarding engine run
solenoid testing procedure.
