Groundsmaster 4500 --D/4700--DPage 5 -- 32Electrical System
Headlight Switch
The headlight switch is located on the operator side of
the console arm (Fig. 34). This two (2) position rocker
switch allows the headlights to be turned on and off.
Testing
1. Park machine on a level surface, lower cutting
decks, engage parking brake and stop engine. Remove
key from ignition switch.
2. Remove console arm covers to gain access to head-
lightswitch(seeConsoleArmintheServiceandRe-
pairs section of Chapter 7 -- Chassis).
3. Disconnect wire harness electrical connector from
the headlight switch.
4. Wit h 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 35. 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 headlight circuit problem
still exists, check wire harness (see Electrical Schemat-
ics and Wire Harness Drawings in Chapter 9 -- Foldout
Drawings).
6. After testing is completed, connect wire harness
connector to the headlight switch.
7. Assemble console arm (see Console Arm Assembly
in the Service and Repairs section of Chapter 7 -- Chas-
sis).
