Parking Brake Sensor - Toro Greensmaster 3150 Service Manual

Parking Brake Sensor

The parking brake sensor is normally closed and opens
when the operator sets the parking brake. If the function-
al control lever is moved out of neutral (neutral switch
opens) and the parking brake is set, the engine magneto
will ground and the engine will stop. The sensor and its
electrical connector are located directly under the oper-
ator foot panel.
Testing
1. Park machine on a level surface. Make sure the en-
gine and ignition switch are OFF. Set brake and block
front wheels.
2. Disconnect electrical connector from the parking
brake sensor.
3. Check the continuity of the sensor by connecting a
multimeter (ohms setting) across the connector termi-
nals.
4. With the parking brake set, there should be no conti-
nuity (open) across the sensor terminals.
5. Release the parking brake. There should be continu-
ity (closed) across the sensor terminals.
6. Connect sensor electrical connector. Reset the park-
ing brake.
