Hi
Pto not engaging on my 6810 or when it does it stops periodically. Replaced switch and solenoid valve but no difference. Fault code 72 shows up which is electrical circuit. I'm told bcu is next to look at. Can this be sent to a dealer for testing/repair? Any advice welcome thanks

Thanks, I followed it from solenoid to where it joins into the loom with wires from speed sensor but I'll try following it to the switch. It's like poking around in spaghetti amongst all that pipes n things!!!

Just had a look there and when I turn the pto on it goes from 001 to 011 for a couple of seconds then 010.and back to 001 when I switch off pto. So you're sure my problem is the bcu then???

I'd say it's the switch. It should change instantly from 001 to 010.
There's a microswitch inside the actual PTO switch. 12v is supplied to it. So, 12v should be coming out as either PTO off when down, then PTO on when lifted and turned.
If the BCU sees both on and off signals, it won't turn it on..
