Seat Switch - Toro Reelmaster 5210 Service Manual

Seat Switch

The seat switch is normally open and closes when the
operator seat is occupied. If the traction system or PTO
switch is engaged when the operator raises out of the
seat, the engine will stop. The seat switch is located di-
rectly under the operator seat.
Testing
1. Before disconnecting the seat switch for testing, the
switch and its circuit wiring should be tested as an ECM
input with the Diagnostic Display (see Diagnostic Dis-
play in the Troubleshooting section of this chapter).
2. If the Diagnostic Display verifies that seat switch and
circuit wiring are functioning correctly, no further switch
testing is necessary.
3. If the Diagnostic Display determines that seat switch
and circuit wiring are not functioning correctly, test seat
switch as follows:
A. Make sure ignition switch is in the OFF position.
B. Disconnect wire harness electrical connector
from the seat switch electrical lead near the manual
tube under the operator seat (Fig. 31).
C. Check the continuity of the switch by connecting a
multimeter (ohms setting) across the switch connec-
tor terminals.
D. With no pressure on the seat, there should be no
continuity between the seat switch terminals.
E. Press directly onto the seat switch through the
seat cushion. There should be continuity as the seat
cushion approaches the bottom of its travel.
F. If seat switch is faulty, replace switch.
G. If the seat switch tests correctly and a circuit prob-
lem still exists, check wire harness (see Wiring Sche-
matic and Circuit Drawings in Chapter 9 -- Electrical
Diagrams).
H. Connect harness electrical connector to the seat
switch.
