aliance antenna rotor
 

I have an old alanice antenna rotor that was given to me. I have a question the rotor has 5 wires but the control box has 4 connections how do i wire up the rotor to the box? The rotor might be a old 100 or 200 u rotor. thanks for any help Robert

You need to get a different control box. What you have is not
compatible. For example a T-20 rotor used a 4 wire connection and a
T-45 used a 5 wire.

You can make it work but it will be Full Manual -- no indicator. The
motor has two coils; the high side of each coil has its own terminal;
the low sides are tied together to another terminal. These three
terminals are powered from a corresponding trio of terminals on the
box, two hots and a common.

The trick to CW or CCW rotation is that one of the hot terminals is
driven directly and the other is driven through a capacitor. The
control box switches the capacitor into one lead or the other,
according to which way you twisted the knob or pressed the lever.

A clever fellow with a multimeter could identify which terminals
belong to which function (on each unit) and connect accordingly.
