Testing the Steering Selector Switch (continued)
Electrical System: Testing the Electrical Components
3. If the InfoCenter verifies that the steering selector switch and circuit wiring
are functioning correctly, no further switch testing is necessary.
4. If the InfoCenter determines that the steering selector switch and circuit
wiring are not functioning correctly, proceed with the test.
5. Remove the control panel to get access to the steering selector switch; refer
to Disassembling the Control Console (page
6. Ensure that the key switch is in the O
electrical connector from the steering selector switch.
7. The steering selector switch terminals are identified in
circuitry of the switch is shown in the
the use of a multimeter (ohms setting), test the switch functions to determine
if continuity exists between the various terminals for each switch position.
Check the continuity between the switch terminals.

Note: The steering selector switch terminals 3, 4, 5, and 6 are not used on
the Groundsmaster 360 machines.
8. Terminals 7 (-) and 8 (+) are used for the indicator light in the switch. The
light should be illuminated when the machine is in 4-wheel steer mode. To
test the switch light, apply 12 VDC to terminal 8 (+) and ground terminal 7 (-).
The light should illuminate.
9. Replace the steering selector switch if testing determines that the switch
is damaged.
10. If the steering selector switch testing is correct and a circuit problem still
exists, check the wire harness; refer to the Electrical Schematics and Wire
Harness Drawings/Diagrams in
11. After you complete the testing, connect the wire harness connector to the
steering selector switch.
12. Secure the control panel to the machine with the removed fasteners; refer
to Assembling the Control Console (page
