Leak Detector Solenoid Valve
The leak detector solenoid valve is a normally open
valve that allows hydraulic fluid to flow from the auxiliary
tank to the main hydraulic tank while the ignition is OFF.
This feature fills the main hydraulic tank with fluid from
the auxiliarytank prior to starting the machine. The valve
closes when the ignition switch is in the RUN position
and during machine operation.
NOTE: For information on leak detector operation refer
to Turf Guardiant Leak Detector System Operation in
this chapter.
Testing
1. Disconnect the wiring connector at the valve sole-
noid.
2. Connect 12VDC power across the solenoid termi-
nals. The valve spool should retract completely.
3. If valve does not retract smoothly or does not retract
completely, replace the valve.
4. To check the solenoid valve supply power, turn the
ignition switch to the RUN position (do not start the en-
gine). Use a multimeter to make sure that the solenoid
valve wire harness connector has 12 volts present.
