Hi- -Low Speed and Headlight Switches
The Hi--Low speed switch is located on the console arm
(Fig. 23). This two position rocker switch allows the trac-
tion speed to be set to high speed (transport) or low
speed (mow).
The headlight switch is located on the operator side of
the console arm (Fig. 23). This two position rocker
switch allows the headlights to be turned on and off.
NOTE: Before disconnecting the Hi--Low speed switch
for testing, the switch and its circuit wiring should be
tested as a TEC input with the Diagnostic Display (see
Diagnostic Display in the Troubleshooting section of this
chapter).
Testing
1. Make sure ignition switch is OFF. Remove key from
ignition switch.
2. Disassemble console arm to gain access to switch
that is to be tested (see Console Arm Disassembly in the
Service and Repairs section of Chapter 7 -- Chassis).
3. Disconnect 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 24. The circuitry of the switch is shown
in the chart below. Verify continuity between switch ter-
minals. Replace switch if testing identifies a faulty
switch.

5. If switch tests correctly and circuit problem still ex-
ists, check wire harness (see Electrical Schematics and
Wire Harness Drawings in Chapter 9 -- Foldout Draw-
ings).
6. After testing is completed, connect wire harness
connector to the switch.
7. Assemble console arm (see Console Arm Assembly
in the Service and Repairs section of Chapter 7 -- Chas-
sis).
