[Elecraft] KIO2 not working

[james at kurtadler.com]

I'm in the process of installing my KIO2. It does not work. I checked 
and re-checked all the wiring, location of the components, etc and 
everything looks good. 

My K2 has the Rev A control board so I had to cut the trace and solder 
some wires (that's the one thing I haven't double-checked yet). I took 
some voltage readings at the data connector on the back of the radio, 
here's what I got:

Pin 1 - 0 volts
Pin 2 - 0 volts
Pin 3 - 0 volts
Pin 4 - 5.59 volts
Pin 5 - 0 volts
Pin 6 - 5.70 volts
Pin 7 - .01 volts
Pin 8 - 14.17 volts
Pin 9 - 8.07 volts

One of the biggest discrepancies I noticed was Pin 2. According to the 
manual, it's supposed to be -8 volts, but I get 0. Any suggestions as 
to where to start looking would be greatly appreciated as I am running 
out of ideas. Thanks!
