Foam Marker Control Switch (Optional)
The foam marker kit control switch is used to control the
flow of foam to the right or left boom. Power to the entire
foam marker system is controlled by the foam marker
ON/OFF switch. The foam marker control switch is
mounted to the left side of the steering column
(Fig. 145).
Testing
1. Park machine on a level surface, stop engine and en-
gage parking brake. Remove key from ignition switch.
2. Locate the foam marker control 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. 149) and the circuitry of the switch is shown
in the chart (Fig. 150). 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 Appendix A − Foldout
Drawings in this manual).
6. After testing, connect the harness connector to the
switch.
