This is an old post from when I had to fix the high flow solenoid...... Gonna go check out PTO switch as I might have a wire loose somewhere under there since I got this error code when doing this repair, but did get pto back going... :confused3:
Re: HIgh flow error 29-03??????? Toolcat 5610 F-series
Repair completed. Was not that bad. Joystick did not have to come off. Side access cover on passenger side, console and top access cover under console had to come off. They slid over the joystick. New solenoid was slightly different and had to grind down plastic hold down nut and use a different o-ring in order for threads to have adequate bite. New solenoid did not have a recess ground into it. Works fine. I must've hooked something up wrong the first go around because PTO would not work and got error 50-78. Took things back apart (just wires on console switches) and reattached everything. Did not find my error, but after that all is well. Error code went away. BTW resistance on new solenoid was about 10 ohm. Old was shorted and read 3 ohms. Good to have the old girl back working properly. I use the 5610 for everything. Probably need to have a backup machine like a v417 or a t190 as well......
