Perhaps before die, the 280A delivered an overvoltage output. That could
explain both the death of the 280A and the short of the K3.
Obviously, I hope to be wrong....

yes cable it's good, there was no fuse on cable from K3 to the supply.
I just check the K3 with a battery and it's seem that the K3 it's in short
circuit.. the battery voltage go to 12v to 0.5v when connected to the K3..
can be the fuse inside the K3 ??

Did you confirm cable and fuses are good?
