Thanks Forkingabout !! That's good to know. I kinda thought that B17:2 to chassis was not a relevant test after I wrote it, so I re-installed the sensor plugged it in fired up the truck and back probed wire at B17:2 and battery negative, I got a constant 48 volts, through a full 360 turn steer event. I figure it's got to switch on and off at some point ? Also If I am right then my new sensor crapped out early? And yes Jim, thought about radial bearing also but end of sensor is unscathed, and clean, and final drive has no real play at all, as far as the radial bearing.
Appreciate all the help.
