Yanmar yt235 pto not working

[Charlieukguy]

PTO light is coming on, but shaft is not turning on the rear or the mid
any one have any ideas if there are any relays fuses etc that could cause this

Start at the switch and fuses…meter them….likely problem. Getting hands on a manual would help. Short of that…work backwards and eliminate the easy switch and fuse. Example: you check for continuity at the pins at the switch (removed)…if the they work it’s not the switch….move to the pins in the plug…you could meter the pins inside the plug….if you don’t know what’s what….also jump the pins inside the plug…if it starts up..it’s the switch, if not etc…but again…without the schematics it’s a process of elimination.
