The power take off (PTO) enable switch is located on the console. This switch is
pulled up to engage the PTO shaft and pushed down to disengage the PTO shaft.
The T1: TEC monitors the position of the PTO switch. Using information from
the PTO switch and other inputs, the T1: TEC energizes the hydraulic solenoid
valve (EH) to engage the PTO clutch.
Testing the Power Take Off (PTO) Switch
The PTO enable 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.
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.
