1. Seat switch
The seat switch is normally open and closes when the operator is on the seat.
The seat switch is part of the safety interlock system. The seat switch is located
directly under the seat cushion. Testing the switch can be done without removing
the seat by disconnecting the seat switch wire harness from the machine wire
harness.
Refer to Figure 81 for this procedure.
1. Park the machine on a level surface, lower any attachments, engage the
parking brake, set the key switch to the O
from the switch.
2. Disconnect the wire harness connector from the seat switch. Check the
harness connector and switch for damage or corrosion and clean or repair
if necessary.
3. Check the continuity of the switch by connecting a multimeter (ohms setting)
across the switch terminals.
A. With no operator in the seat, should be no continuity between the
terminals.
B. Press directly onto the seat switch through the seat cushion. There should
be continuity as the seat cushion approaches the bottom of its travel.
4. Replace the switch if necessary.
5. If the seat switch testing is correct and the circuit problem still exists, check
the machine wire harness; refer to
6. Connect the wire harnesses to the switch and test the seat switch operation
before returning the machine to service.
