SRT5K with 3 each SRT192 batteries

[hankcsmith]

Have a SRT5K that gives me a RBC 1 not connected alarm.  I have 3 RBC's connected.  The second RBC has a red light flashing.  I did a deadhead/cold restart.  I did move batteries from RBC 1 to RBC 2 to see if the red light issue followed. It did, so I put the batteries from RBC1 to RBC 3 so that I could eliminate the 3rd RBC from the system until batteries could be brought is.  But when I did this the 2nd RBC light came back on.
