OK... so NONE of that worked... So, I reinstalled everything and
checked it 3 times...
Here is something....
What should the voltage be on Pin #1 of P95 (XV12DC) be with respect to
chassis?
I am reading 13.75 VDC
Confirming what the picture APPEARS to be in the manual for the
connection of the 1-wire, 3-pin connector to the 3-pin 12V power IN on
the 2 meter module:
As you are looking at the open top of the K3s from the front, over the
front panel....
Does the connector plug in such that the 1-wire is on "Pin #3" on the 2
meter module (IAW, the pin closest to the PA shield/rear of the chassis?
I took the PCB out of the 2 meter module enclosure and inspected the
pins and traces on the PCB....
Pin #1 trace appears to be a (+) line which is bypassed to ground with a
n SMD device... believe it was stenciled as a cap (input filtering of
some sort)? (Pin #1 to Pin #3 is approx. 0.2 Ohms)
Pin #2 solders to the ground plane on the bottom of the PCB. (0.1 Ohms
or so between Pin #2 and enclosure; Open from Pin#2 to Pin #3)
Pin #3 appears to be the unfiltered (+) as it leads to a rather large
trace on the bottom of the board leading from the connector to the
interior of the board.
So the power wire from P95/Pin #1 goes eother to Pin #1 or Pin #3 on the
2 meter module 12V IN. The picture in the manual APPEARS to be Pin #3
and it follows, as the connector has Pin #1 marked and Pin #1 is
traditionally on the left side of a PC Board header.
I'm running out of ideas...

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...

Just what the title says.... I installed a new K144XV and Reference
Oscillator Phase Lock Option tonight.
When I hit the band switch to go up to the 2 meter band, it thru a
HIGH CURR error.
I followed the directions in both install manuals precisely (as
appropriate for a K3s as enhanced), and double checked BOTH sets of
steps after getting the error.
IF I disco the power, wait, reconnect, and then power up (provided I
switch bands out of 2 meters), the error goes away. But if I switch
back to 2 meters, it throws the error again.
I am going to go in and remove the REFLock option and try to just get
the K144XV to "work".
The status light flashes just as described in the manual for "normal
operation". (once or twice on power up, then OFF)
I've verified the supply voltage and current are "normal" 14.2 VDC
at 1.47 amps (higher because the subRX was installed a couple days ago.
Any ideas as to what is causing this "issue"? I'm missing all my
weekend nets. <wink>
