Pto Solenoid Valve Coil; Testing - Toro Z Master 7500-D Series Service Manual

PTO Solenoid Valve Coil

The hydraulic system of the machine uses a solenoid valve coil (Figure 17) on the front of the transmission to
engage and disengage the cutting deck. When the solenoid valve coil in energized, hydraulic flow is directed to
operate the wet clutch, integral to the transmission.

Testing

NOTE: Do not remove the solenoid from the cartridge for testing.
1. Ensure that the key switch is in the OFF position. Unplug the wire harness electrical connector from the
solenoid 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 0.5Ω 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 two connector terminals of the solenoid coil.
NOTE: The resistance of the solenoid coil must be approximately 7.5Ω.
3. Connect the wire harness connector to the solenoid coil.
