I am  trying to install the KSBS2 into my K2.

Problem symptoms are that I get  the Hi Current warning, plus I get no 
variance on my separate receiver  when trying the fine balancing.

The rest of the alignment went okay,  SSBA on BAL gave me good nulls 
with tweaking R1 both on USB and LSB (I  just cannot hear any null with 
the receiver. I get a very strong carrier  (S9+) on my separate receiver 
with SSBA at 3.

It has not come up in any replies to your question, but it looks that you  
may be getting problems with RF into your microphone socket and the KSB2 audio  
input.
 
Are the KSB2 tests being carried out into a good 50 ohm dummy load?
 
There have been various methods described on the list for combatting  
problems of RF getting into the microphone input, the main one being to provide  a 
ground on the microphone socket outer.
