SOLENOID VALVE (3-POSITION/SINGLE SOLENOID) - (CONTINUED)
1.
Chock Wheels.
2.
Remove wiring connectors from 2 solenoids (Figure 3, Item 4 and 5).
3.
Turn ignition switch on; release hand brake, place transmission gear selector in reverse.
4.
Measure the voltage across both reverse input connectors (Figure 1, Item 3).
5.
Voltage measured should be 12 volts nominally.
D1
Forward Solenoid Voltage Tests
1.
Chock Wheels.
2.
Remove wiring connectors from 2 solenoids (Figure 3, Item 1 and 5).
3.
Turn ignition switch on; release hand brake, place transmission gear selector in D1.
4.
Measure the voltage across both D1 input connectors (Figure 1, Item 3).
5.
Voltage measured should be 12 volts nominally.
D2
Forward Solenoid Voltage Tests
1.
Lift vehicle all 4 wheels (WP 0028).
2.
Remove wiring connectors from 2 solenoids (Figure 3, Item 2 and 6).
3.
Start vehicle; release hand brake, place transmission gear selector in D2.
4.
Allow wheels to spin fast enough to which would allow transmission to shift into 2nd gear.
5.
Measure the voltage across both D2 input connectors (Figure 1, Item 3).
6.
Voltage measured should be 12 volts nominally.
D3
Forward Solenoid Voltage Tests
1.
Lift vehicle all 4 wheels (WP 0028).
2.
Remove wiring connectors from 3 solenoids (Figure 3, Item 1 and 2).
3.
Start vehicle; release hand brake, place transmission gear selector in D2.
4.
Allow wheels to spin fast enough to which would allow transmission to shift into 3rd gear.
5.
Measure the voltage across both D3 input connectors (Figure 1, Item 3).
6.
Voltage measured should be 12 volts nominally.
