CIRCUITS
ON 2 + 3, 5 + 6
OFF 2 + 1, 5 + 4
The optional hazard switch is located on the steering column control pod. When
the forward end of the hazard switch is depressed, power is sent to the flasher
module to illuminate the hazard lights (switch light illuminated). The hazard lights
will continue to flash until the switch is returned to the O
FF
(rearward) position.
The hazard switch receives power from a 15 Amp fuse located in the cab power
supply harness (along the frame crossmember in front of the engine).
Testing the Hazard Switch
1. Park the machine on a level surface, lower the cutting unit (or attachment),
engage the parking brake, set the key switch to the O
FF
position and remove
the key from the key switch.
2. Disconnect the battery negative (-) cable at the battery; refer to Removing
and Installing the Battery (page 6–64) .
3. Remove the steering column control pod cover.
4. Disconnect the wire harness electrical connector from the hazard switch.
Check the switch and the harness connector for damage or corrosion and
clean or repair if necessary.
5. Use a multimeter (ohms setting) and the preceding table to determine
whether continuity exists between the various terminals for each switch
position.
6. Replace the hazard switch if necessary.
7. If the hazard switch testing is correct and a circuit problem still exists, check
the wire harness; refer to Appendix A (page A–1) .
8. Connect the wire harness to the hazard switch.
9. Install the control pod cover.
