Seat Switch - Toro Sand Pro 5040 Service Manual

Seat Switch

The seat switch is normally open and closes when the
operator is occupying the seat. The seat switch is lo-
cated directly under the seat. If the operator leaves the
seat, the engine will stop unless the traction pedal is in
the neutral position.
The closed seat switch (seat occupied) and diode D1
keep the interlock relay energized and the engine run-
ning when the traction pedal is depressed.
Testing
1. Park machine on a level surface, lower attachment,
stop engine, apply parking brake and remove key from
ignition switch.
2. Tilt up operator seat and locate seat switch for test-
ing.
3. Disconnect harness electrical connector from the
seat switch.
4. Check the continuity of the switch by connecting a
multimeter (ohms setting) across the switch terminals.
5. With no pressure on the seat, there should be no
continuity between the seat switch terminals.
6. Press directly onto the seat switch through the seat
cushion. There should be continuity as the seat cushion
approaches the bottom of its travel.
7. Connect harness electrical connector to seat switch
after testing.
