[Elecraft] K2 Was Fine Now Dead?

[Don Wilhelm]

Allan,

Was that J5, the 3 pin connector point (no header is normally installed 
there) on the RF Board near the front center (near the control board)?

If you did everything correctly, it should have no effect on the K2 
power-up condition.  If you wired to some other place than the 3 pin J5, 
remove what you added and try to discover what the error is.

It may have been something that inadvertently happened, and not at all 
associated with your additions - in that case, voltage measurements are 
in order.  You may have had a pin pushed back on the AUX DC connector 
from the KPA100, and it is no longer making contact with P3 on the RF 
Board - insert the crimp pins into the housing correctly if you find 
that to be the problem.

Is the KPA100 ribbon cable properly attached to the control board?
These are but a few starter questions.

73,
Don W3FPR
