I have a 8243 White planter with hydraulic drive. The drive will not run today it seems the solinoid is not openning and allowing the oil to the drive motor. I have the problem narrowed to the solinoid or the control modual which one would be more likely? After a few seconds the monitor in the cab starts to flash sensor. I figure that is do to not getting any movement from the drive motor. It is a RIchardey John drive if that helps.

Thanks

Brian
