High Flow Hydraulics Switch (Vehicles with High Flow Hydraulics)
On vehicles equipped with the high flow hydraulics kit,
the switch to engage the high flow hydraulic circuit is
mounted on the dash (Fig. 20). When the high flow hy-
draulics kit switch is ON, the solenoid coil on the control
manifold is energized to allow hydraulic flow to the at-
tachment. An indicator light on the high flow hydraulics
switch identifies when the switch is ON.
Testing
1. Park machine on a level surface, stop engine, apply
parking brake and remove key from ignition switch.
2. To ease access to high flow switch, remove hood of
vehicle (see Hood in the Service and Repairs section of
Chapter 5 − Chassis).
3. Locate high flow hydraulics switch on dash and dis-
connect wire harness electrical connector from the
switch.
4. With the use of a multimeter (ohms setting), the
switch functions may be tested to determine whether
continuity exists between the various terminals for each
switch position. The switch terminals are marked as
shown in Figure 21. The circuitry of this switch is shown
in the chart below. Verify continuity between switch ter-
minals for each switch position. Replace switch if testing
proves it to be faulty.

5. Replace high flow hydraulics switch if testing proves
it to be faulty.
6. After testing, connect wire harness electrical connec-
tor to the high flow hydraulics switch.
7. Install hood if it was removed (see Hood in the Ser-
vice and Repairs section of Chapter 5 − Chassis).
