the elevator was long ago converted to freight status only ( no people) per tx regulations. there was no accident.a water htr had to be hauled up from the basement. at this time the bldg does not warrant "modernizing the elevator" if it did i would of done it. such an upgrade would not increase or add to the value of the bldg.that said i would stil appreciate being able to procure said wiring diagram. as a freight only elevator it poses no danger - real or imaginary - thank you
