Parking Brake Switch - Toro Groundsmaster 4000-D Service Manual

Parking Brake Switch

The switch used for the parking brake is a normally open
switch that is located under the steering tower cover
(Fig. 24). When the parking brake is not applied, the
parking brake pawl depresses the switch plunger to
close the switch. When the parking brake is applied, the
parking brake pawl is positioned away from the switch
plunger so the switch is in its normal, open state.
Testing
1. Make sure the engine is off. Locate parking brake
switch for testing.
2. Disconnect wire harness connector from the switch.
3. Check the continuity of the switch by connecting a
multimeter (ohms setting) across the connector termi-
nals.
4. When the switch plunger is extended there should
not be continuity between the switch terminals.
5. When the switch plunger is depressed, there should
be continuity between the switch terminals.
6. After testing, connect switch connector to wire har-
ness.
