Worklight Switch
The worklight switch is located on the control panel
(Fig. 51). This rocker switch allows the worklights
(headlights) to be turned on and off.
Testing
1. Park machine on level surface, lower cutting units,
stop engine, apply parking brake and remove key from
ignition switch.
2. Remove cover from control panel to gain access to
worklight switch.
3. Disconnect wire harness electrical connector from
the worklight switch.
4. With the use of a multimeter (ohms setting), the
worklight switch functions may be tested to determine
whether continuity exists between the various terminals
for each position. The switch terminals are marked as
shown in Figure 52. The circuitry of the worklight switch
is shown in the chart below. Verify continuity between
switch terminals.
