Can still hear motor whining/whirring when raise is commanded but forks do not raise. playing with tilt fixes it... seems like it has a "bad spot" in a certain tilted position that throws out the lift/lower... i've pulled off the lift/lower and auxiliary valve blocks, took them apart did not find anything wrong. tried a different pressure relief valve on the lift/lower valve, problem still occurs. tried a different solenoid on the lift/lower manifold.. same problem. not sure what else I can try

thanks
