See Figure 39.
All models have a N.O. (normally open) seat switch.
When the seat is unoccupied, the switch is open and will
not conduct current. Sitting in the seat closes the switch.
1. Tilt the seat forward and pull the wire harness off the
back of the switch.
2. Set VOM to Ohm. With the switch at rest (no operator
pushing down on the seat) probe the switch termi-
nals. The VOM should show no continuity (open).
3. Press down in the middle of the seat to activate the
switch.
4. Probe the switch terminals. The VOM should show
continuity
5. Replace a switch that does not pass all tests.
