We have a EJE 116; 2005 with a AS2405F AC controller. We replaced the drive potentiometer: the flatcable was broken after a fall out of the lorry.

Now the truck drives good in drivers direction. But in forkdirection it only drives when the accelerator is turned half. When turned to full throttle it stops.

Does it need calibration? Can this be done by the pin code pad? Or do we have an other problem. (With the old accelerator the truck only drives full speed).
