Seat Switch; Fuse Block - Toro Greensmaster 3150 Service Manual

Seat Switch

The seat switch is normally open and closes when the
operator is on the seat. If the Functional Control Lever
is moved out of neutral (neutral switch opens) and the
operator raises out of the seat, the engine magneto will
ground and the engine will stop. The switch and its elec-
trical connector are located directly under the seat.
1. Make sure the engine and ignition switch is Off. Re-
move seat from the support assembly by removing four
lock nuts from the seat bolts.
2. Disconnect electrical connector from the seat
switch.
3. Check the continuity of the switch by connecting a
multimeter (ohms setting) across the connector termi-
nals.
4. With no operator in the seat, there should be no con-
tinuity between the 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. Connect switch electrical connector. Reinstall seat.

Fuses can be removed to check continuity. The test me-
