Fuel Stop Solenoid
ThefuelstopsolenoidusedonyourReelmastermustbe
energized for the diesel engine to run. The solenoid is
mounted to the injection pump on the engine (Fig. 58).
The Electronic Control Module (ECM) monitors the op-
erationof thefuel stopsolenoid.The solenoidanditscir-
cuit wiring should be tested as an ECM output with the
Diagnostic Display (see Special Tools and Trouble-
shooting in this chapter).
If the ECM detecteda fuel stop solenoid problem during
engine operation, the Diagnostic light can be used to
identify the fault (see Diagnostic Light in the Trouble-
shooting section of this chapter).
Testing
1. Park machine on a level surface, lower cutting units,
stop engine, apply parking brake and remove key from
ignition switch. Open hood to gain access to engine.
2. Disconnect wire harness connector from fuel stop
solenoid.
NOTE: The fuel stop solenoid may be removed from
the engine or tested in place.
3. If the solenoid is removed from the engine, make
sure that the solenoid plunger moves freely and is free
of dirt, debris and corrosion.
NOTE: Prior to taking small resistance readings with a
digital multimeter, short the testleads together. Theme-
ter will display a small resistance value (usually 0.5
ohms or less). This resistance is due to the internal re-
sistance of the meter and test leads. Subtract this value
fromthe measuredvalue ofthecomponent youaretest-
ing.
4. Using a digital multimeter (ohms setting), touch one
test lead to the pull coil terminal and the other test lead
to the fuel stop solenoid frame (ground) (Fig. 59). The
resistance of the pull coilshould be less than 1 ohm(but
not zero).
5. Using a digital multimeter (ohms setting), touch one
test lead to the hold coil terminal and the other test lead
to the fuel stop solenoid frame (ground) (Fig. 59). The
resistance of the hold coil should be approximately 15
ohms.
6. If either coil resistance is incorrect, replace fuel stop
solenoid.
7. Connect wire harness c onnector to the fuel stop so-
lenoid.
8. Lower and secure hood.
