Hi there I have a problem with a Boss electric with the steinbock power steer controller similar to the Jungheinrich Keltronic units. Steer only works in one direction (it uses a 3 terminal power steer motor), swapped the motor cables around on the steer unit and the motor now turns in other direction. The sensor in the steer column appears to have correct voltage as i turn the steering either way (2.5v-0 and 2.5-5v). The steinbock power steer controller was stripped and checked it appears to be ok. Any ideas? Dont have any information on this controller. Any information on the steinbock power steer controller would be appreciated then i can bench test the unit in the workshop.
