Seat Switch
The seat switch is normally open and closes when the operator is on the seat. The seat switch and its electrical connector are located in the seat assembly. If the trac- tion system or PTO switch is engaged when the operator raises out of the seat, the engine will stop. Testing of the switch can be done without seat removal by disconnect- ing the seat wire from the machine wiring harness (Fig. 25).
Testing
1.Make sure the engine is off.
2.Disconnect wire harness electrical connector for the seat switch.
3.Check the continuity of the switch by connecting a multimeter (ohms setting) across the connector termi- nals.
4.With no pressure on the seat, there should be no continuity between the seat switch terminals.
5.Press directly onto the seat switch through the seat cushion. There should be continuity as the seat cushion approaches the bottom of its travel.
6.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
7.Connect seat switch to harness connector after test- ing is complete.
