[Roy Wiglesworth]

Hope someone can help me I need a wiring / circuit
diagram for the controlbox that controls the motor
drive for the  US Tower HTX 472  ha been working
fine everyday  but yesterday when i went to raise it
nothing seems to be one master relay in there that is not
energizing if i manualy push it closed i can make the
tower go up or down .
thanks for any help i know us tower doesn't give you
much paper work.
