Ham Series Modification 

If you have ever soldered wires at all, this modification is quick and easy.  Please 
refer to Figure 1 below.  Remove the bottom cover of your Ham series control 
box.  Find the two wires going to the center brake switch.  Remove one of the 
wires and solder it to the other wire on that switch.  In the photo, the green wire 
was moved to the black wire.  Replace the cover. 
 
If you have a new series Ham rotor, you have a Jones plug (8 pin rectangular) 
socket on the rear of your control box.  In this case, take the new Jones plug 
supplied with your RC1-H and your included power cord, and connect the cord to 
pins 1 and 2.  Pin 1 should go to the barrel side of the coax plug and pin 2 to the 
tip. 
 
If you have an older Ham series with a terminal strip.  Mark the wire numbers on 
your rotor cable then remove your rotor cable from the old control box.  Wire 
them up pin 1 to 1, pin 2 to 2, pin 3 to 3, etc. to the new Jones plug.  Take the 
two ring terminals and solder or crimp them to the ends of the included power 
cord.  Pin 1 should go to the barrel side of the coax plug and pin 2 to the tip.  
Now you can use your old control box’s power switch as a power switch for your 
new RC1-H.
