I would like to know if someone has a generic wiring diagram for a rotator with nine wires coming out of the bottom. The color of my wires are - green, yellow, brown, orange, white, red, black and 2 other black wires connected together. This rotator is at least 30 years old,  the outside looks very good.  I am thinking about opening it up and checking the inside but first I would like to find out if someone has a diagram of the inside too. The only name I can find on it is a  TRA 4. Someone have any suggestions? Thanks
