I have two US Tower HDX-589MDPL towers. When I purchased them, both
control boxes on the towers were extremely rusted inside and in terrible
condition. I started from scratch and built 2 new control boxes with all
new components. Also, I replaced the cables running from the control box to
the limit switches to the motor, and to the 120v power source. (I also
replaced each motor, as they were in really bad condition and locked up).
I enclosed each of these cables in flexible conduit with watertight
fittings. I simply used the UST wiring diagram and made mine exactly like
the original ones. It's very simple and very inexpensive.
I paid around $45 at Home Depot for each metal weatherproof box, and all
the other components are very cheap. I may have spent $100 total on each
completed box. They now look and function like new.
