Matt is entirely correct. The first thing to investigate in the event
of a Hi Current message is the voltage (as indicated by the K3) level
during transmit.
The way Elecraft transceivers control power, a low voltage means that
higher current must be obtained to maintain the requested power output
level.
Common causes are loose connections at the power supply, improperly
assembled Anderson PowerPole connectors, and either long power supply
cables or too small a wire gauge resulting in significant voltage drop
when current is drawn.
This applies not only to the K3, but also to the KXPA100 and the K2/100.

I see the same thing, but only on 10m. I just assumed (possibly erroneously)
the power indication was not accurate and used the indicated 100w. I don't
have an external wattmeter to validate. My antenna is tuned for 20m so tuning
it is not that hard on 10m.

Maybe there is not enough voltage at the power input to the radio —
possibly due to high resistance at your power connections or in your
fuse holders?
