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 (Fig. 15). If the operator
leaves the seat, the engine will stop unless the motion
control handles are in the neutral locked position.
The closed seat switch (seat occupied) keeps the en-
gine running when the motion control handles are
moved from the neutral locked position.
Testing
1. Before removing the seat switch for testing, the
switch and its circuit wiring should be tested with the
Hour Meter Module (see Hour Meter Module in this
chapter). If the Hour Meter Module verifies that the seat
switch and circuit wiring are functioning correctly, no fur-
ther switch testing is necessary. If, however, the Hour
Meter Module determines that the seat switch and cir-
cuit wiring are not functioning correctly, proceed with
seat switch testing.
2. Make sure ignition switch is OFF. Remove key from
ignition switch.
3. To access seat switch, remove seat support plate
with attached operator seat from machine (see Operator
Seat in the Service and Repairs section of Chapter 6 -
Chassis).
4. Disconnect machine wire harness connector from
the seat switch.
5. Check the continuity of the switch by connecting a
multimeter (ohms setting) across the seat switch con-
nector terminals.
6. With no pressure on the seat, there should be no
continuity (open circuit) between the seat switch termi-
nals.
7. Press directly onto the seat switch through the seat
cushion. There should be continuity (closed circuit) as
the seat cushion approaches the bottom of its travel.
8. If testing determines that seat switch is faulty, re-
place seat switch (see Operator Seat Service in the Ser-
vice and Repairs section of Chapter 7 - Chassis).
9. Connect wire harness connector to seat switch after
testing is complete.
10.Secure seat support plate with attached operator
seat to machine (see Operator Seat in the Service and
Repairs section of Chapter 6 - Chassis).
