Jim,
What is your power supply voltage as reported by the K3 when transmitting? As
power supply voltage drops the K3 increases current in order to put out the
requested power. If the voltage is dropping too low this can result in the
hi-cur message.
Also, the threshold for the hi-cur message is adjustable in theK3's tech mode
menu, I believe.

While transmitting some JT9 at 100w on 6m yesterday and watching the
voltage display on the K3 menu I occasionally saw a HI CUR message which
then disappeared after less than a second.
I've never seen this before. I was monitoring the voltage after putting in
some new cabling from the PS and it has made the supply voltage more
stable. The K3 now reads no less than 12.5v while transmitting 100w.
Not sure where to start or just to forget about it until it shows a
persistent fault.
SWR is low and feedlines are 7/8" hardline so I don't think there's a fault
in those. If there was I'm sure it would be more evident with the KPA500 at
full tilt but there's no such indication.
I do have the KPA3 replacement pins kit which I've not yet installed. Is
this fault associated with those pin issues?
Thanks
