Greensmaster 3250--D Page 5 -- 29 Electrical SystemFuel SolenoidThe 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 onthe engine (Fig. 36). The fuel solenoid is energizedwhen the ignition switch is in either the RUN or STARTposition.The fuel solenoid includes two (2) coils for operation: thepull coil and the hold coil. When the ignition switch isturned to START, the fuel solenoid pull coil is energizedand the solenoid plunger retracts. Once the plunger isretracted, the hold coil will keep it retracted for continuedengine operation. When the solenoid is de--energized,the plunger extends to shut off fuel supply to the enginecausing 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 shouldfail, the fuel solenoid will not function and the engine willnot run. Refer to electrical drawings in Chapter 10 --Foldout Drawings when troubleshooting the fuel sole-noid.NOTE: See Kubota Workshop Manual, Diesel Engine,SM--E3B Series for information regarding fuel solenoidtesting procedure.Figure 361.
