[Johnson] Johnson Rotomatic Question

[Chris Kepus]

Greetings to the list,

I just snagged a Rotomatic Rotator controller.   Pictures are still up for
it on eBay, Item 230966496604.  After receiving it and checking out its
internals, it looks like it has been hacked.  Don't know to what extent
because I have not been able to find any info on it using Google or BAMA or
anything else! 

My version has three switches:  left switch is power, middle switch is
CW/CCW rotary switch, the far right being "Relay on/off".  No indicator lamp
and the needle pointer is very slim.  Black with an arrow on one side, red
and plain on the other.  The dial is illuminated from behind.  

Anyone out there who can assist with a wiring diagram?  Pictures of unhacked
internals? 

Not looking for the rotator (although I would love to see one of these
brutes), I have a prop pitch motor and selsyn set up with which I want to
use the Rotomatic controller.

Thank for any and all info, comments, etc.
