A rotator unit this old probably has a dead phase shift motor capacitor in  
the control box. Over time the electrolyte dries out and the capacitor turns  
into a resistor.
New capacitors are available from Hygain as a CD45 replacement.

Cool -  thanks for all the advice and links to the manual - -it looks at this
point  like it will do what i need quite nicely -- the load will be fairly
light  and is as follows:

1 -  5 element arrow antennas uhf beam
1 -  13 element 2 m beam
1 - 3 element 6m beam
1 - 10-15-20 m Rotatable  dipole

the location that im putting it all is fairly wind shaded, and i  have had
the same load up on a standard TV rotor for some time  now.

I hooked up the rotor quickly last night to try it out and the  lights on the
control box functioned, but the rotor did not turn, so  hopefully tonight i
will have some time for troubleshooting.  IM  hoping i made a bad hookup
someplace and that the motor is not burned out  or some such thing.

Any way -- its exciting to see the tower project  comming together - i should
be getting my top bushing this weekend, and  then once the rotor works, i can
start loading the mast

hope you all  have a great day

73 and good DX
