I just recently purchased a used (three years old) US Tower TX 472 MDP with
the factory installed motor and limit switches. It has the control box
mounted on the tower.  The tower worked fine when I purchased it and at
home when it was tilted over.  I raised it today for the first time.  It
cycled up to the 72 foot height and the limit switch stopped it as it
should.  I lowered it back to the minimum height and the lower limit switch
stopped it perfectly.   I tried to raise it back up and nothing happens,
just lime there is no power to the unit.  I checked the power coming into
the control panel and everything seems fine there. I suspect that perhaps
the upper limit switch may be stuck or may have malfunctioned.

I have no documentation for trouble shooting thjis problem.  I am in need
of documentation (wiring diagram, schematice, etc) for this set up and will
pay someone for copying and mailing expenses.

Any help or advice on this problem will be greatly appreciated.
