Windshield Wiper/Washer Switch (Groundsmaster 4010--D)
The windshield wiper/washer switch is used to control
operation of the windshield wiper and washer pump on
the Groundsmaster 4010--D. The windshield wiper/wa-
sher switch is located in the cab headliner (Fig. 46).
Testing
1. Make sure ignition switch is OFF. Remove key from
ignition switch.
2. Remove switch plate from cab headliner.
3. Locate windshield wiper/washer switch and unplug
wire harness connector from switch.
4. The switch terminals are marked as shown in Figure
47. The circuit logic of the wiper/washer switch is shown
inthechartbelow.Withtheuseofamultimeter(ohms
setting), the switch functions may be tested to determine
whether continuity exists between the various terminals
for each position. Verify continuity between switch termi-
nals. Replace wiper/washer switch if testing identifies a
faulty switch.
