Multi Pro 5800Page 6 − 68Electrical System
Fuel Run/Stop Solenoid (Diesel Engines Only)
The fuel stop solenoid must be energized for the engine
to run. It is mounted to the injection pump on the engine
(Fig. 101).
In Place Testing
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.
1. Park machine on a level surface, stop engine and en-
gage parking brake. Remove key from ignition switch.
2. Disconnect wire harness connector from solenoid.
3. Using a digital multimeter, touch one test lead to the
pull coil terminal and the other test lead to the fuel stop
solenoid frame (ground) (Fig. 102). The resistance of
the pull coil should be less than 1 ohm (but not zero).
4. Using a digital multimeter, touch one test lead to the
hold coil terminal and the other test lead to the fuel stop
solenoid frame (ground) (Fig. 102). The resistance of
the hold coil should be approximately 15 ohms.
5. Connect harness wire connector to the solenoid.
Live Testing
1. Park machine on a level surface, stop engine and en-
gage parking brake. Remove key from ignition switch.
2. Disconnect wire harness connector from solenoid
and remove the solenoid from the engine.
3. Make sure that the solenoid plunger moves freely
and is free of dirt, debris and corrosion.
4. Connect a positive (+) test lead from a 12 VDC
source to the pull coil and hold coil terminals.
5. Touch a negative (−) test lead from the 12 VDC
source to the fuel stop solenoid frame (ground) (Fig.
102). The solenoid should engage, making an audible
“click,” and the plunger should retract.
6. Remove positive (+) voltage from the pull coil termi-
nal. The solenoid should stay engaged.
7. Remove positive (+) voltage from the hold coil termi-
nal. The solenoid should release.
8. When testing is complete, install the solenoid to the
engine and connect wire harness to the solenoid.
