Parking Brake Switch
The parking brake switch is normally open and closes
when the parking brake is applied. The brake switch is
attached to the frame on the right side of the operator
seat (Fig. 11). If the operator seat is not occupied, the
engine can be started if the parking brake is applied and
the motion control handles are in the neutral locked pos-
ition.
Testing
1. Before removing the parking brake switch for testing,
the switch and its circuit wiring should be tested with the
Hour Meter Module (see Hour Meter Module in this
chapter). If the Hour Meter Module verifies that the park-
ing brake switch and circuit wiring are functioning cor-
rectly, no further switch testing is necessary. If, however,
the Hour Meter Module determines that the parking
brake switch and circuit wiring are not functioning cor-
rectly, proceed with parking brake switch testing.
2. Make sure ignition switch is OFF. Remove key from
ignition switch.
3. Disconnect machine wire harness connector from
the parking brake switch.
4. Check the continuity of the switch by connecting a
multimeter (ohms setting) across the parking brake
switch connector terminals.
5. With the parking brake released, there should be no
continuity (open circuit) between the parking brake
switch terminals.
6. Apply the parking brake. There should be continuity
(closed circuit) between the parking brake switch ter-
minals.
7. If testing determines that parking brake switch is
faulty, replace parking brake switch.
8. Connect wire harness connector to parking brake
switch after testing is complete.
