Anyone know why the G-800SA manual specifies 6 conductor cable when only 4 
conductors are actually used??  I got a brand new in the box G-800SA off 
ebay for my second tower this month, and I checked the manual and it shows 
that on the rotor end you should wire 1-6 and 7 is unused.  And they give 
you the shell and 6 contacts for the controller box end as well.  But if you 
look in the female connector on the back of the controller only four 
positions have contacts in them, 2,3,4,5, number 1 and 6 are empty.

Any reason why you would want a wire connected to pins 1 and 6 on the rotor 
end when there is nothing inside connected to it on the controller end?? 
The schematic shows that pin 1 on the rotor is the other side of the 
position pot, and pin 6 is not connected.

The only benefit of using 6 wire cable is if any of the other conductors 
became broken you would have a couple spares if you folded them back at each 
end.

I have this rotor's predecessor on my other tower, a G-800S, and that one 
has a 6 conductor plug on each end and only five wires are used according to 
the manual.  Of course I wired it up with 6 wire cable.  Comparing the 
schematics it would appear the older G-800S does have a connection to pin 1 
in the controller, there is a cap across pin 1 and pin 2.

I took a piece of four conductor cable and put it between the controller and 
the rotor on my new G-800SA and it worked perfectly, figured it would since 
the controller doesn't have any contacts in positions 1 and 6, so it would 
appear I can use four conductor cable instead on this one.  Ok, so why all 
the bother??  Well with copper prices as they are, I can get 4 conductor 
cable cheaper than 6 conductor cable and even go up a step in size to say 
16awg on all four conductors for the same price as 6 conductor cable which 
has 2 18awg and 6 22awg.
