[QUOTE="BC873G, post: 101471, member: 14887"] Hi, here are a few things I would try before hauling it to Frankfort. 1. You said you calibrated the actuators. Did you check the neutral voltage after you reinstalled them to see if they still measure 1.72 volts? From my experience the input voltage from the controller has not been exactly 5 volts and they seem to respond to input proportionally. My experience is with an AHC controller though. 2. When you had the actuators off did you check to make sure the spool valves returned to center easily? If not the spools could be sticking and would result in the same error. 3. Make sure you tighten the actuator bolts evenly. They have tendency to be mis-aligned and binding can result. When I replaced mine I removed the control panel so I had a lot of room from the top to access them. 4. Did you swap the actuators from lift to tilt when you reinstalled them? If you do remove them check the centering of the spool values I would swap them and see if error code moves to 32-39 consistently. That would be more of indication that the actuator is bad. Were your spool valve seals leaking at all? Good luck and hope this helps to keep you from hauling it in. [/QUOTE]
