Seat Switch

Purpose

The switch is in the safety circuit. If the engine is running
and the operator vacates the seat with either the PTO or
the parking brake disengaged, the engine will shut down.
Note: There is a delay module in the system,
located in the hour meter module; there will
be a slight delay before the engine shuts
down after the operator vacates the seat.

Location

The seat switch is mounted under the seat to the seat
frame (Fig. 494).

How It Works
When the seat is vacated, the switch is open and there
should be NO continuity between the two terminals.
When the seat is occupied, the switch closes and there
should be continuity between the two terminals (Fig.
495).

Testing

1. Disconnect the switch from the wiring harness.
2. Using a VOM, check first to ensure there is NO
continuity between either terminal, plunger out.
3. With the plunger pushed in, there should be
continuity between the terminals.
