Testing
1. Park machine on level surface, lower cutting units,
stop engine, apply parking brake and remove key from
ignition switch.
2. Before disconnecting the joystick switches for test-
ing,theswitchesandtheircircuitwiringshouldbetested
as a TEC electrical input using the Diagnostic Display
(see Diagnostic Display in the Troubleshooting section
of this chapter). If input testing verifies that the joystick
switches and circuit wiring are functioning correctly, no
furtherswitchtestingisnecessary.If,however,inputtes-
tingdeterminesthatthejoystickswitchesandcircuitwir-
ing are not functioning correctly, proceed with the
following joystick switch testing procedure.
3. Remove console cover from console assembly to
gain access to joystick switches (see Control Console
Disassembly in the Service and Repairs section of
Chapter 7 -- Chassis).
4. Make sureignitionswitchisintheOFF position.Dis-
connect wire harness connectors from joystick
switches.
5. Check the continuity of the raise switch by connect-
ing a multimeter (ohms setting) across the switch con-
nector terminals as follows:
A. Withthejoystickintheneutralposition,continuity
should only exist between the common and NC ter-
minals.
B. With the joystick in the raise position, continuity
should only exist between the common and NO ter-
minals.
6. Check the continuity ofthe lower switch byconnect-
ing a multimeter (ohms setting) across the switch con-
nector terminals as follows:
A. Withthejoystickintheneutralposition,continuity
should only exist between the common and NC ter-
minals.
B. With the joystick in the lower position, continuity
should only exist between the common and NO ter-
minals.
7. Replace joystick switch if necessary.
8. After switch testing is completed, connect the har-
nessconnectorstothejoystickswitches.Installconsole
cover (see Control Console Assembly in the Service
and Repairs section of Chapter 7 -- Chassis).
