Bruce,
I would expect a Hi REFL message rather than Hi Cur if SWR was the problem.
Check your power supply connections. If you have bolts and nuts on the
power supply output terminals, if the bolts turn (even slightly) when
you tighten the nuts, you will have to dig inside the power supply to
fully tighten the bolts to the lugs on the inside.
With Elecraft gear, a low power supply voltage will result in a higher
current draw from the power supply. Elecraft gear seeks to maintain the
requested power output, and a low supply voltage means that the current
must increase to maintain the power level.

To the list:
I occasionally get the Hi Current warning on my K3. I notice it cuts my
power back about 10% from 100w. My initial assumption is that my SWR is
too high - but the SWR meter is easily less than 2.0 I run the ATU which
confirms SWR about 1.2 or so.
So what am I missing - something bad in my transmission line?
