Switch, Parking Brake (Manual PTO)
Location
The parking brake switch is located under the fuel tank
near the locking lever (Figure 16).
Purpose
The parking brake switch is part of the safety interlock
system. The engine will shut down if the operator
leaves the seat without engaging the parking brake.
How It Works
When the parking brake is latched, the plunger is
depressed, closing the contacts (fi gure 17).
Testing
1. Disconnect the switch from the wiring harness.
2. Use a ohmmeter to test continuity between the
terminals (fi gure 17).
Plunger out – no continuity
Plunger in - continuity
