my 16ft lund steering is problematic. When steering to right or left while going fast the steering does not work. The wheel turns but the motor has not. I replaced the cable 3 years ago because the steering wheel was so hard to turn. Maybe I missed something while installing?? I can simulate that action by holding the motor while someone turns the steering wheel. Also when turning the steering wheel it never will stop. On a car it goes only so far right or left then no more. Can anyone trouble shoot my issue? Thank u, David
