I have a 773F. It is throwing a code HF 1-6 on BOSS. (Manual says this code means the hydro-static charge filter sensor has no signal). The BICS is flashing 3 times on the valve light. The lift and tilt do not work. Would the charge filter sensor cause the lift/tilt not to work? If not, what are the symptoms of the charge filter sensor not getting signal?
As to the hydraulics, I considered that it might be a separate issue. My understanding is that the valve light flashing on the BICS 3 times, means that the green wire is shorted. Typically this a result of a bad solenoid, but I have replaced the valve stem and the magnetic coil solenoid on the main hydraulic box. I also tested all wires to make sure I had continuity and all passed. I then thought it was the BICS unit, but I hot wired around that to no avail.
It seems that if start it and hit the pedals right away, the lift/tilt works more often. If I wait, it does not work at all. When it does work the hydraulics stay working until I turn it off. Any thoughts on what to do to solve intermittent tilt/lift not working?
