How It Works
Contacts inside the switch electrically connect various
terminals in both "On" and "Off" position. When the
PTO is pulled out to the ON position, current flows to
the electric clutch and it engages. When the switch is
pushed in to OFF position, current flows through the
PTO switch to the Park Brake switch as part of the circuit
used to ensure safe starting.
Testing
1. Disengage the PTO, set the parking brake, and turn
the ignition to OFF and remove the key.
2. Remove the 4 screws holding the control panel to
the fuel tank.
3. Disconnect the wiring harness from the PTO switch.
4. Press in the locking tabs, on each side of the switch,
and pull the switch out of the control panel.
