[Elecraft] K3 won't shut off, turns on by itself

[Don Wilhelm]

Coy,

That sounds like something is pulling the ACC connector pin 8 to ground 
(see Remote Power On in the manual).
I would remove everything from the ACC connector as a quick test. If 
that does not stop it you will have to contact Elecraft support, but if 
it powers on normally with nothing plugged into the ACC connector, you 
will have to check your cables and other equipment carefully.
