Seat Switch
The seat switch is normally open and closes when the operator is on the seat. If
the traction system or PTO switch is engaged when the operator raises out of
the seat, the engine shuts off. The seat switch and its electrical connector are
located directly under the seat (
Figure 155 ).
The Standard Control Module (SCM) monitors the status of the seat switch. If
the key switch is in the O
N
position and the seat is occupied, the SCM In seat
input LED should be illuminated.
Testing the Seat Switch
1. Before you disconnect the seat switch for testing, ensure that you test the
switch and its circuit wiring as a SCM input; refer to Standard Control Module
(page 5–3) .
2. If the SCM verifies that the seat switch and circuit wiring are functioning
correctly, then no more switch testing is necessary.
3. If the SCM determines that the seat switch and circuit wiring are not
functioning correctly, then test the seat switch as follows:
A. Ensure that the key switch is in the O
FF
position. Tilt the seat assembly
up to get access to the seat switch electrical connections.

Note: There is a short wire harness that is used to connect the seat
switch to the main wire harness of the machine. This seat switch harness
is between the seat and the seat plate.
B. Disconnect the machine wire harness electrical connector from the seat
switch harness electrical lead under the operator seat ( Figure 155 ).
C. Connect a multimeter (ohms setting) across the seat switch harness
connector terminals to check the continuity of the seat switch.
D. With no pressure on the seat, ensure that there is no continuity between
the harness terminals of the seat switch.
E. Press directly onto the seat switch through the seat cushion. Ensure that
there is continuity between the harness terminals of the seat switch as
the seat cushion approaches the bottom of its travel indicating that the
seat switch is functioning.
