The key switch on the console has three (3) positions − OFF, ON and START.
The key switch is an input used by the T1: TEC to manage various machine
functions.
Testing the Key Switch
The key switch and its circuit wiring can be tested as a T1: TEC input using the
InfoCenter Display; refer to
Using the InfoCenter Display for Troubleshooting
(page 3–23)
. If testing determines that the switch and circuit wiring are not
functioning correctly, proceed with the following test procedure:
1. Park the machine on a level surface, lower any attachments and stop the
engine.
2. Disconnect the battery negative (-) cable at the battery.
3. Remove the instrument panel from the console.
4. Disconnect the wire harness connector from the switch and remove the
switch from the instrument panel if necessary.
Note:
Key switch terminals 1 and 6 are connected internally. Terminals 4
and 5 are also connected internally. These terminals should have continuity
regardless of the switch position.
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 switch if necessary.
7. If the switch tests correctly and a circuit problem still exists, check the wire
harnesses; refer to
Appendix A (page A–1)
.
8. Install the switch, connect the wire harness and install the instrument panel
after testing.
9. Connect the battery negative (-) cable at the battery.
