It shows removing the console beside the seat, pulling the PTO switch, and using a multimeter to test continuity on the prongs to confirm the switch itself (not the solenoids) was at fault, caused by moisture freezing inside it. Useful for owners troubleshooting the exact same no-PTO symptom.
Posted by the Conrad Gingerich channel, an owner working through his own tractor's repair rather than a dealer or professional technician.
In this case it was the PTO switch, not the solenoids. Moisture or snow got inside the switch and froze, preventing it from opening all the way and engaging the PTO.
Remove the console beside the seat, pull out the switch, and use a multimeter set to continuity. With the switch closed, outside prongs should beep; opened, outside-to-inside prongs should beep instead.
Take off the console beside the seat, which is held by two bolts underneath and two screws, then pull the switch out after pushing in its tab buttons.
