[Elecraft] K3s throwing a "HIGH CURR" error after installing K144XV and Reference Phase Lock Option

[Clay Autery]

Update...

1) Strictly speaking, removing the RefLock option board and associated 
SINGLE TMP cable did not "fix" anything... Still have the "HIGH CUR" error.
2) Incidentally, IF you fire the K3s up on ANY other band (after disco 
and reconnecting power to clear error) WITH the KXUSB cable connected to 
the computer AND the K144XV "RS-232" port, and THEN switch from any 
other band TO 2 meters, the status light flashes once as expected (ready 
for firmware).  BUT, the K144XV Utility will NOT connect to the K144XV.  
Then, of course, if you shut the K3s down while on 2M band and remove 
the KXUSB cable from its port, then power back up....

a) Powers up, status light flashes once or twice as expected.
b) the K3s shows ANT3 briefly, and then starts trying to display the 
power-on banner, but is interrupted repeatedly by the HIGH CUR error.... 
which remains after the banner scroll completes.
c) You have to power down, and disco/reconnect the power to reset.

I pulled the left side of the case off ans inspected the IF IN and IF 
out cables to verify that they are connected correctly AND still fully 
plugged, and had NOT been pinched off.

I think I will try again, with the ANT 3 cable disconnected to remove 
the BNC cable assembly as a possible cause....  I'm reaching here now.

_*Question:*_  Is there any chance that having the "grip" portion of ANY 
of the TMP connectors making contact with the K144XV enclosure a 
"problem"?  The ANT3 TNP board connector is set at a slightly OFF angle, 
and the TMP outer (coax shiield) might be touching the enclosure.  Just 
trying t figure out what is "wrong", and if it anything I have control 
over...

73,
