Spray−Mode Switch (ExcelaRate Spray Systems Only)
The spray−mode switch is located on the left side of the
instrument panel (Fig. 61) and is used to select between
Auto and Manual spray mode control.
Testing
1. Park machine on a level surface, stop engine and en-
gage parking brake. Remove key from ignition switch.
2. Locate the switch to be tested and disconnect the
wire harness electrical connector from the 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
position. The switch terminals are marked as shown
(Fig. 66) and the circuitry of the spray−mode switch is
shown in the chart (Fig. 64). Verify continuity between
switch terminals.

4. Replace switch if necessary.
5. If the switch tests correctly and a circuit problem still
exists, check the wire harnesses (see Electrical Sche-
matics and Wire Harness Drawings and Diagrams in
Chapter 11 − Foldout Drawings in this manual).
6. Connect the wire harness connector to the switch af-
ter testing is complete.
