Hi Everyone-

I am involved in Nissan forward and reverse problem.
The initial problem was to change the directional handle(very loose), I did it and after that, the unit can not move either forward or reverse, I have checked pumps and they are ok, also the traction motor by push in main and forward contactors.

Brand - Nissan
Electric - Control using a SCR (it is not familiar to me)
Model - CYB02
Serial - CYB02 - 000380
Capacity - 5000 lb

Let me know where to start, the control is not familiar to me and I do not want to perform more complicated problems.

Battery voltage is 36.7

The unique contactor is operated is the steer one none else.

Thank you
