One of my customers has a wave 50 that would shutter when turning and so he replaced both left and right drive motor. He had no codes whatsoever until he installed the new motors. Now the new motors show right motor open and left motor open. If I take the old motors and leave them out of the truck and connect them the unit powers up like it should. We pushed the unit around in tow mode but still no fix. I am going back tomorrow with 2 new motors and a controller but was seeing if anyone else experienced this issue before. Hopefully I explained myself good enough!
