Martin,
One thing to check is the blades in the Anderson PowerPole connector at
the end of the cable.
Peer into the end of the cable - if you see the ends of two metal blades
in either side of the connector, the contact blade has not been fully
seated behind the securing spring - give it a hard push with a screwdriver.
The other thing to check is the tightness of the terminals on the power
supply.
The burned connector inside the K3 will usually only affect power to the
KPA3, and it will usually produce an ERR 12V condition rather than a
shutdown. That problem has been cured some long time ago when the pins
were changed to gold plated type - if you do not have an early K3, that
condition is not likely.

Hi Ron,
I'm glad I found your email as my K3 (#5426) has been experiencing the same
issues for a couple of days. I did not dismantle it for now to see if it's
related to the burned connector issue as I would like to try it with
another power supply first (and i need to borrow one first from another
ham).
This K3 was used extensively on Reunion Island during 10 days lately as
part of the TO7CC DX Expedition, maybe this has made the issue to appear
now. First I thought that it was related to the power supply but then it
happened at least once when the K3 was on RX. I upgraded the MCU and
DSP1/DSP2 to the latest softwares but that did not resolve the issue.
Let me know if you manage to track your issue down !
