[Elecraft] The ERR 12V Message Question

[Bill Stravinsky]

 The problem is in the male and female connectors.  I don't think a shorter power cable will do anything.  There is no substitute for replacing the connectors.When I had mine act up Elecraft sent me the wrong parts.  I had a contest coming up and wouldn't have enough time to get the correct parts.  I took the boardout and cleaned the pins (you could see they were discolored and needed replacing).
That worked for the upcoming contest and didn't fail all weekend and for 2 or 3 more weeks then the ERR 12v fault returned.  I had received the correct partsshortly after the contest weekend and did the replacement.  All has been fine since.  That was almost two years ago.

p.s.  The complete repair took a lot less time than I thought, an afternoon as I recall.

 It's been a while since I did mine but I think disassembly/reassembly 
was a significant part of the effort. I did the front panel connector at 
the same time as the power connector. The actual removal of the 
connectors and soldering new ones went pretty quickly. I'm not sure I'd 
want to go through the disassembly for a "quick fix" only to have to do 
it again in another month.

You might want to refer to online blogs about the process, or Youtube 
videos (if any). Sorry, I don't have the links, but one hint: after you 
snip the connectors off the board use an alligator clip to grasp the pin 
stubs for desoldering; it's easier than trying to manage it with a pair 
of dikes.
