1999 bobcat: ran great..electrical connectors at the actuators..wiring…

1999 bobcat 773 (s/n XXXXXXXXX with 1300 hrs; recently purchased; ran great for about 12 hrs then: tilt function stopped, but lift and all other functions continued working; lift (left) handle displayed 5 blinking lights which manual says is actuator problem (1) i switched top and bottom electrical connectors at the actuators: tilt control switched to lift handle (left) and lift control switched to tilt handle (right); now tilt function works but lift function does not; the right handle always causes the fault, whether it is lift or tilt and left handle always works whether it is lift or tilt q1.1: does this prove that both actuators and valve spools are working properly since lift and tilt could be made to work by switching the wiring? q1.2: is one valve spool and acuator dedicated to lift and the other to tilt? if yes, since there is a top and bottom - which is lift and which is tilt (2) i then switched the handle solenoids (same p/n and each side) and this changed nothing q2.1: does this prove that these solenoids are not the problem (3) whether wired to control lift or tilt, the right handle (problem handle) if moved outward very slowly would work properly until all the way outward and then it would fault; right handle (problem handle) if moved inward even slightly would immediately fault (4) i hope it is not the main controller - $1200 part; any ideas any ideas??  XXX-XXX-XXXX (office) XXX-XXX-XXXX (fax) XXX-XXX-XXXX (mobile)[email protected]
