Hazard Light Switch (Optional)
The hazard light switch is located on the instrument pan-
el to the left of the ignition switch (Fig. 158). The switch
includes a light that should illuminate when the switch is
in the ON position. The hazard light and horn circuits are
protected by a 15 amp fuse (FB4 5−6).
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. 159) and the circuitry of the switch is shown in the
chart (Fig. 160). Verify continuity between switch termi-
nals.
4. To test switch light, apply 12 VDC to terminal 8 (+)
and ground terminal 7 (−). The light should illuminate.
5. Replace switch if necessary.
6. 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
Appendix A − Foldout Drawings in this manual).
7. Connect the wire harness connector to the switch af-
ter testing is complete.
