does it have a monotrol pedal? --- ?park brake switch?
Hi Rmullis,
Is there no fault code shown with this problem, if not it would suggest that no direction had been selected, in which case the direction switch may be faulty, these switches are not wired but magnetic, these switches just pull out from the housing but do it carefully you should be able to swop it with the indicator switch. Try that see if you get a result, if you can access the error log there may be some fault codes logged and may need deleting or rectifying.
