Hour Meter; Seat Switch - Toro Greensmaster 3150 Service Manual

Hour Meter

The hour meter is located on the control panel.
Testing
1. Connect the positive (+) terminal of a 12 VDC source
to the positive terminal of the hour meter.
2. Connect the negative (--) terminal of the voltage
source to the other terminal of the hour meter.
3. The hour meter should move a 1/10 of an hour in six
(6) minutes.
4. Disconnect the voltage source from the hour meter.
5. Replace the hour meter if necessary.

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 op-
erator 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.
Testing
1. Make sure the engine and ignition switch is OFF.
2. Remove seat from the support assembly by remov-
ing four (4) lock nuts from the seat bolts.
3. Disconnect electrical connector from the seat switch.
4. Check the continuity of the switch by connecting a
multimeter (ohms setting) across the connector termi-
nals.
5. With no operator in the seat, there should be no con-
tinuity between the terminals.
6. Press directly onto the seat switch through the seat
cushion. There should be continuity as the seat cushion
approaches the bottom of its travel.
7. Connect switch electrical connector.
8. Secure seat to support assembly with removed fas-
teners.
