Headlight Switch - Toro Groundsmaster 4500-D Service Manual

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-
light switch (see Console Arm in the Service and Re-
pairs section of Chapter 7 -- Chassis).
3. Disconnect wire harness electrical connector from
the headlight 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 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.

connector to the headlight switch.
7. Assemble console arm (see Console Arm Assembly
