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 Func-
tional Control Lever is moved out of neutral (neutral
switch opens) and the parking brake brake is set, the en-
gine magneto will ground and the engine will stop. The
sensor and its electrical connector are located directly
under the operator foot panel.
1. Park machine on a level surface. Make sure the en-
gine and ignition switch is Off. Set brake and block front
wheels.
2. Disconnect electrical connector from the parking
brake sensor.
3. Check the continuity of the switch by connecting a
multimeter (ohms setting) across the connector termi-
nals.
4. With the parking brake set, there should be no conti-
nuity across the switch terminals.
