This machine is an A/C unit with on demand steering. Most of the time it works great but some times the power assist is reduced by about 50% ( including motor speed ) but still responsive to steer wheel movement. When steer assist is reduced and I unplug the three wire plug at the motor, it goes in to high and I have full assist but goes back to reduced steering when plugged back in.
I replaced the steer sensor on the column and the trigger wheel on the column shaft is ok.
Is it the master or traction controller operate voltage for this function and how to check.
Thx
