CK3510SE HST - PTO fuse blowing

[cholland]

Anyone have the shop manual or a wiring diagram for the PTO circuit on a ck3510se, share a picture?

I have a 2019 CK3510SE HST, with the electronic PTO type switch.
I recently noticed the PTO light would come on even without PTO being engaged. Then one morning the tractor would not start. Upon inspection I find the 5A PTO fuse is blown. If I replace the fuse, I can start the tractor, but within 5-10 seconds the fuse will blow. The tractor remains running, but if I shut it down it will not start until I replace the 5A PTO fuse.
Sometimes the PTO light is on when I initially start, sometimes it is not. Of course once the fuse is blown the PTO will not engage. Everything else operates without issue. I haven't used the PTO in about 3 months. I have checked the PTO auto disengage is turned off.

Pretty sure I'm dealing with some type of short, continuity issue in the PTO circuit, but don't have the shop manual available so I can't trace the circuit. I know there is a relay, a switch, the auto switch, a solenoid and something obviously goes through the starting circuit so you don't start with it engaged.
It is under warranty, I called the dealer, they are about 1 week out on being able to take a look. Hoping I can trouble shoot the problem and expedite the repair. And as many of you know the warranty covers parts and labor, but not the actual service call.

Is your 4WD light on as well? If so, could be a short in the PTO solenoid. Try locating the PTO solenoid and disconnecting, and then see if the tractor will start. If it starts, try turning on the PTO. If the fuse remains intact, it's likely the PTO solenoid.

See this link for someone else having a similar issue. The link also has a picture further down in the discussion trail that shows roughly what the PTO solenoid looks like and where it's located.

No, 4WD light is not on. It never comes on, never has. I am almost always in 4WD, lots of hills. I just figured that light was for another model.

I looked at the link shared above. That is for a DK, mine is a 2019 CK. I don't know how much difference there is but it looks like my solenoid is on the left side. There is only one wire bundle coming to it, so I assume that is for the PTO. I didn't get a chance to really troubleshoot today. Dentist appointment, and other things happened.

My inexpensive multimeter fried. Batteries corroded. I cleaned it up but it still doesn't function correctly. Ordered a new one, should be here in two days.

Anyone have the schematic for a PTO circuit on a CK3510SE they can share?

reviving an old thread, I'm having the exact same issue with my Ck3510SE, can you share how you fix it please?

I ended up calling the dealer, cause warranty. They had it for a couple of days and fixed it. Something about a diode in the wiring harness. I don't know where or exactly what they did but it hasn't been a problem since.
I did go through quite a few fuses in that week or so waiting for them to pick it up. In the end it didn't cost me anything but the fuses.

Thanks for the update!
