Massey Ferguson 3065 Hidraulic / Electric Problem

[vasyj04]

Hi everyone! I have a 3065 for over a year and i had various problems with him. ( Broken front 4wd axel, 4wd always engaged, unable to disengage diff lock after some time
after I went with him coupled, solenoid problems, RUST , the tractor wasn't moving becouse of a wire etc ) but this problem that i have now is very annoying, so last month i went sowing and my sower got stuck on the up position, i tried all the button but nothing, can it have a dead spot where it locks? After i arrieved home the next day it was working fine.

Battery live and earth connections first then trace the yellow and red wires from the fuses near the air filter down to the battery and down to the auto tronic box under the rh cab front looking for broken or corroded wires.

So, the second time it got locked up, I got home, I tried to verify all the cables from the autotronic, I dont know what I did, but the tractor didn't wanna go, and I had the low pressure light on the dashbord. The problem was the pressure switch who has been changed to a newer version and added a resistor to it, that resistor was broken. I fixe the resistor sand I had the tractor moving but the 3 point hitch was still locked în the up position.( one of the thick yellow wires was out of its spot so I placed it back)

The lift control valve is mounted on the left side cover just in front of the rear axle. It has 2 solenoids on it, they have buttons on them that can be pressed to override the electrics and prove its not a hydraulic problem. Does your control panel wake up when you wiggle the togglle switch?

Yes, its lighting up, but when I turn the switch to the up/down position, I can't hear the pump.

On a 3080 there are some multi-pin connectors under the left side bonnet. Wd 40 spray fixed my ELC problems

Are you sure the linkage isn't jamming somewhere.
Pick up hitch rods being the obvious place if you have them

I tried to wiggle the sower and jump on it, but nothing.
