Operator Seat Switch
The seat switch has normally open contacts that close
when the operator seat is occupied. The seat switch is
located directly under the operator seat. The Toro Elec-
tronic Controller (TEC) monitors the operation of the
seat switch (input). The machine will not start it the oper-
ator seat is unoccupied and the parking brake is not en-
gaged.
Testing
The seat switch and its circuit wiring can be tested as a
TEC input or qualifier using the InfoCenter Display (see
InfoCenter Display − Diagnostics Screen in this
chapter). If testing determines that the switch and circuit
wiring are not functioning correctly, proceed with the fol-
lowing test procedure:
1. Park machine on a level surface, stop engine and en-
gage parking brake. Remove key from ignition switch.
2. Raise and support operator seat to access seat
switch harness connector.
3. Disconnect wire harness electrical connector from
the seat switch harness (Fig. 122).
4. Check the continuity of the switch by connecting a
multimeter (ohms setting) across the switch harness
connector terminals.
5. With no pressure on the seat, there should be no
continuity (infinite ohms resistance) between the seat
switch terminals.
6. Press directly onto the seat switch through the seat
cushion. There should be continuity (zero ohms resis-
tance) between the seat switch terminals as the seat
cushion approaches the bottom of its travel.
7. If testing determines that seat switch is faulty, re-
move the seat and replace switch.
8. If the seat switch tests correctly and a circuit problem
still exists, check wire harness (see Electrical Schemat-
ic and Wire Harness Drawings in Chapter 11 − Foldout
Drawings in this manual).
9. After seat switch testing is completed, connect wire
harness electrical connector to the seat switch. Lower
and secure seat.
