Fuel Stop Solenoid<br />
The fuel stop solenoid must be energized for the engine<br />
to run. It is mounted to the injection pump on the engine<br />
(Fig. 37).<br />
In Place Testing<br />
NOTE: Prior to taking small resistance readings with a<br />
digital multimeter, short the test leads together. The meter<br />
will display a small resistance value (usually 0.5<br />
ohms or less). This resistance is due to the internal resistance<br />
of the meter and test leads. Subtract this value<br />
from the measured value of the component you are testing.<br />

2. Using a digital multimeter, touch one test lead to the<br />
pull coil terminal and the other test lead to the fuel stop<br />
solenoid frame (ground) (Fig. 38). The resistance of the<br />
pull coil should be less than 1 ohm (but not zero).<br />
3. Using a digital multimeter, touch one test lead to the<br />
hold coil terminal and the other test lead to the fuel stop<br />
solenoid frame (ground) (Fig. 38). The resistance of the<br />
hold coil should be approximately 15 ohms.<br />
4. Connect solenoid to the wiring harness.<br />

2. If the solenoid is removed from the engine, make<br />
sure that the solenoid plunger moves freely and is free<br />
of dirt, debris and corrosion.<br />
3. Connect a positive (+) test lead from a 12 VDC<br />
source to the pull coil and hold coil terminals.<br />
4. Touch a negative (–) test lead from the 12 VDC<br />
source to the fuel stop solenoid frame (ground) (Fig. 38).<br />
The solenoid should engage, making an audible “click,”<br />
and the plunger should retract.<br />
5. Remove positive (+) voltage from the pull coil terminal.<br />
The solenoid should stay engaged.<br />
6. Remove positive (+) voltage from the hold coil terminal.<br />
The solenoid should release.<br />
7. Reconnect the wires to the solenoid.<br />
