Elecrafters,
the K3 all of a sudden shut down twice during my vacation/portable 
operation. I thought i had identified the problem by tightening a loose 
wire in a 220V-outlet of my /p home.

Now it shut down a third time (i believe the refrigerator turned on the 
same moment) and this seems to be a tough one.

The display shows 12V ERR on transmit , the power will not go above 12 
Watts and when i set it above 12 Watts i see 12V ERR , CHECK CIRCUIT 
BREAKER. The Fan runs continuosly at mid-level.

Where to start? The only gear for measuring is a DMM here.

BTW: The Switcher PSU delivers rock solid 13.8 Volts.
There is no way to reload the Firmware right now, i have no cable  here.
