Hi--Low Speed and Headlight Switches
TheHi--Low speedswitchislocated ontheconsole arm
(Fig.23).Thistwopositionrockerswitchallowsthetrac-
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
DiagnosticDisplayintheTroubleshootingsectionofthis
chapter).
Testing
1. Make sure ignition switch is OFF. Remove key from
ignition switch.
2. Disassemble console arm to gain access to switch
thatistobetested(seeConsoleArmDisassemblyinthe
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
continuityexists between thevariousterminalsforeach
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,checkwireharness(seeElectricalSchematicsand
Wire Harness Drawings in Chapter 9 -- Foldout Draw-
ings).
6. After testing is completed, connect wire harness
connector to the switch.
7. Assembleconsolearm(seeConsoleArmAssembly
