| We had your problem last year got it fixed now Check your amperage and volts at 7 pin plug at tractor,Check your grounds ,,run a test ground wire from tractor battery to ground the hydraulic manifold that has the 5 solenoid valves, 3 sv3 for raising folding unfolding and 2 sv4 for markers,
If you price 7 p valve -and the other two 5s they are SV3 valves approximately $350 each but kenzi has the same valve for $60 and replace the coils kenzi has them also at good price . These replacement valves have same specs and screw right in manifold
Check your amperage from power We had coils taking 13 amps and heating up coils Disconnect wire at 7p check amperage also 5
Now we have amperage at valve 7p and 5r or 5p at each one 1.7 amps and no heating coils
You also might want to check your main harness for shorts but we replaced our harness still had the problem till we replaced coils and valves
Those valves will sometimes stick open or close screwing up folding
Sv3 valves when not energized oil flows only in one direction, when energized valve is lifted off its seat and oil goes both ways
