Parking Brake Switch
Purpose
How It Works
The Parking Brake Switch is part of the safety circuit.
The parking brake switch is used to shut down the
engine if the machine leaves neutral with the parking
brake on (Fig. 737).
This is a “Normally Closed (NC)” switch. The letters
“NC” will be stamped on the terminals. When the parking
brake is engaged, the switch is closed and there is
continuity between the switch terminals.

Location
The Parking Brake Switch is located inside the LH side
of the control panel, as part of the parking brake control
lever assembly (Fig. 738).

Testing
Turn the ignition key to the run position (do not start
the machine). While observing the black triangle for the
parking brake indicator on the hour meter, engage and
disengage the parking brake. If the black triangle turns
on and off, the switch is good.
If the black triangle for the parking brake indicator
fails to turn on when the parking brake is engaged
and disengaged, the switch needs to be checked for
continuity.
1. Disconnect the switch from the wire harness.
2. With a multimeter set to the “Ohms” setting or a
continuity light, verify that there is continuity between
the terminals (plunger out).
3. With the plunger pushed in, there should be NO
continuity between the terminals.
