Hey Guys,

Working on a Raymond RTW40 / 3 wheel sitdown. Zapi control system. Unit while turning left, LH drive motor continues to drive and not cut out or change direction for smooth turning. RH side works great. Trouble shot contactors, steer encoder, cable set up, ect. Noticed while turning left the contactor for the LH side does not disconnect like the RH side. Thinking the steer encoder sends a signal to the controller, controller sends signal to the contactor, I made an adjustment to the encoder with the same results. I'm leaning towards a controller replacement, but wanted to check with anyone out there that might have some input on this system. Thanks for any help.
