Operator Presence Switch (Seat Switch)

Operator Presence Switch (Seat Switch) Testing
Neutral Switch — Left and Right

Parking Brake Switch

Electrical: Service and Repairs
With the ignition switch in the RUN position, and the operator presence switch
closed (operator is in the seat), battery voltage is supplied to the left hand neutral
switch.
Note: The operator presence switch is part of the seat assembly.
1. Disconnect the wire harness from the operator presence switch, located
on the bottom of the seat assembly.
2. Using a digital multi-meter set to the OHM or Continuity setting, test the
continuity between the 2 switch terminals.
• When the seat is vacated, the switch should NOT have continuity (open).
• When the operator is present, the switch should have continuity (closed).
•
The neutral switch is a single pole plunger type switch (normally open) with
two terminals. When the plunger is depressed, the circuit closes and there
is continuity between the terminals.
•
Motion control levers in neutral position (OUT), the switch should have
continuity (closed).
•
Motion control levers in the operating position (IN), the switch should NOT
have continuity (open).

•
The parking brake switch is a dual pole/four terminal plunger type switch
(normally open and normally closed). When the parking brake is set
(engaged), the normally closed pole of the switch is open and the normally
open pole is closed. This allows proper voltage and ground signal path for
the safety interlock and PTO operations.
•
Parking Brake ON, the switch should have continuity (closed).
•
Parking Brake OFF, the switch should NOT have continuity (open).
