Testing the Lower/Raise Joystick Switches
1. Park the machine on a level surface, lower the cutting units, set the parking
brake, and shut off the engine.
2. Before you disconnect the joystick switches for testing, ensure that you test
the switches and its circuit wiring as TEC input with the InfoCenter display;
refer to
Using the InfoCenter Display for Troubleshooting (page 7–28) .
3. If the InfoCenter verifies that the joystick switches and circuit wiring are
functioning correctly, no further switch testing is necessary.
4. If the InfoCenter determines that the joystick switches and circuit wiring are
not functioning correctly, proceed with the test.
5. Remove the control arm covers to get access to the joystick switches; refer
to Disassembling the Control Arm (page 8–23) .
6. Ensure that the key switch is in the O
FF
position. Disconnect the wire
harness electrical connectors from the raise and lower switches on the
joystick assembly.
7. Connect a multimeter (ohms setting) across the switch connector terminals
to check the continuity of the switches as follows:
A. With the joystick in the N
EUTRAL
position, continuity should only exist
between the common and normally closed (NC) terminals.
B. With the joystick in the R
AISE
position (raise switch) or L
OWER
position
(lower switch) continuity should only exist between the common and
normally open (NO) terminals.
8. Replace the switch if testing determines that the switch is damaged.
9. If the switch testing is correct and a circuit problem still exists, check
the wire harness; refer to the Electrical Schematic and Wire Harness
Drawings/Diagrams in
Appendix A (page A–1) .
10. After you complete the testing, connect the wire harness connectors to the
joystick switches.
11. Secure the control arm covers to the machine; refer to Assembling the
Control Arm (page 8–25) .
