Seat Switch
The seat switch is normally open and closes when the
operator is on the seat. The seat switch and its electrical
connector are located in the seat assembly. Testing of
the switch can be done without seat removal by discon-
necting the switch wire from the machine wire harness
(Fig. 42). The seat switch is an input used by the Toro
Electronic Controller (TEC) to manage various machine
functions.
Testing
The seat switch and its circuit wiring can be tested as a
TEC input using the InfoCenter Display (see InfoCenter
Display in this chapter). If testing determines that the
switches and circuit wiring are not functioning correctly,
proceed with the following test procedure:
1. Park machine on a level surface, lower cutting units,
engage parking brake and stop engine. Remove key
from ignition switch.
2. Disconnect seat switch connector from the machine
wire harness connector.
3. Check the continuity of the switch by connecting a
multimeter (ohms setting) across the seat switch con-
nector terminals.
4. With no pressure on the seat, there should be no
continuity between the seat switch terminals.
5. Press directly onto the seat switch through the seat
cushion. There should be continuity as the seat cushion
approaches the bottom of its travel.
6. If seat switch is faulty, replace switch.
7. If testing determines that seat switch is faulty, re-
place seat switch (see Operator Seat Service in Chap-
ter 8 − Chassis in this manual).
8. Connect seat switch connector to wire harness con-
nector after testing is complete.
