I have connected my test-istruments to the logic card, so it can not be cable problem. I have checked sensorbearing with osciloscope, fork-rotator potentiometer, and the end-stop sensors. I have also changed lever between sideshift/reach and rotate. The sensor bearing change was the first thing I did, before I started look for other. Synkro-movement (automatic change from one side to the other) works perfect, until you want to reach for a pallet. A bad sensor or harness would stop the synkro also, wouldn't it?
