Oh, I didn't mean to be a wise guy Mr. P body. Sorry if I came across like that.

I worked and taught Navy equipment for years. It was funny as there was several "rumors" as to how one should turn off the hydraulic system, and also when to turn off a certain circuit breaker.

People had been living by these "rules" for years, yet none of it was documented in the book, because it was all hearsay baloney. I fought that BS for over 20 years to get rid of that behavior. I wouldn't doubt they are back at it now though, it would only take one actor to start the crap all over again, even though it was never in the book procedure.

That's why I mentioned the instructions, the documentation for us guys.
