Electrical System
Foam Marker Kit ON/OFF Switch (Optional)
The foam marker kit ON/OFF switch is used to enable
the foam marker system. The flow of foam to the right or
left boom is controlled by the foam marker control
switch. The foam marker ON/OFF switch is located on
the control console below the InfoCenter display
(Fig. 87).
Testing
1. Park machine on a level surface, stop spray pump,
stop engine and engage parking brake. Remove key
from ignition switch.
2. Remove console panel. Locate the foam marker ON/
OFF switch and unplug wire harness connector from
switch.
3. 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 (Fig. 88) and the circuitry of the switch is shown
in the chart (Fig. 89). Verify continuity between switch
terminals.
4. Replace switch if testing determines that it is faulty.
5. If the switch tests correctly and a circuit problem still
exists, check wire harness (see Electrical Schematic
and Wire Harness Drawings in Chapter 10 − Electrical
Drawings in this manual).
6. After testing, connect the harness connector to the
switch. Install console panel to machine.
