Fuel Stop Solenoid - Toro Reelmaster 7000-D Service Manual

Fuel Stop Solenoid (Kubota Diesel Engines Only)
The fuel stop solenoid used on your Reelmaster
7000−D must be energized for the diesel engine to run.
The solenoid is mounted to the injection pump on the en-
gine (Fig. 64).
The Toro Electronic Controller (TEC) monitors the op-
eration of the fuel stop solenoid. The solenoid and its cir-
cuit wiring should be tested as a controller output with
the Diagnostic Display before following the testing pro-
cedure listed below (see Special Tools and Trouble-
shooting in 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 test leads together. The me-
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
from the measured value of the component you are test-
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. 65). The
resistance of the pull coil should 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. 65). 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 connector to the fuel stop so-
lenoid.
8. Lower and secure hood.
