Solenoid valve and coil
The hydraulic system of the Groundsmaster 7210 machine uses a solenoid valve
coil on the front of the transmission (
). When the solenoid valve coil is
energized, hydraulic flow is directed to operate the PTO system.
The Standard Control Module (SCM) provides current to the solenoid valve coil
based on the position of several inputs. The PTO LED on the SCM is illuminated
when the solenoid valve coil is energized.
Testing the PTO Solenoid Valve Coil
Note:
Do not remove the solenoid from the cartridge valve for testing.
1. Ensure that the key switch is in the O
FF
position. Unplug the wire harness
electrical connector from the solenoid valve coil.
Note:
Before taking the small resistance readings with a digital multimeter,
short the multimeter test leads together. The multimeter displays a small
resistance value (usually 0.5 ohms or less). This resistance is because of the
internal resistance of the multimeter and test leads. Subtract this value from
the measured value of the component that you are testing.
2. Measure the resistance between the 2 connector terminals of the solenoid
coil.
Note:
The resistance of the solenoid coil must be approximately 7.5 ohms.
3. Connect the wire harness connector to the solenoid coil.
4. If the solenoid coil requires replacement; refer to
