I used to know all that stuff. As an instrumentation startup engineer, I activated the instrumentation on the GE turbine at Cholla Unit 4 in Joseph City, AZ. I checked out the auxiliary packages and everything.
But that was twenty years ago...sigh.
If you worked out in that corner of the world did you ever run across a man named JR Robinson, or Jim Fox. I knew both of them and they were working out there at that time.
