If you are in CW mode, you will need to use some form of CW key
to create output. (Without a key down, zero output is normal.) A
key plugged into the radio will work fine. You can also play
back a CW memory (that has something in it), to produce output.
I'm away from my K3, but I think you can produce output by
putting it in Data->FSK-D or Data->PSK-D might also work.
Using TUNE on the radio is another way for force output.
When using wsjt-x, you should be able to hear the audio signal
from the computer via the Monitor function. You should hear the
audio after turning the monitor level up a bit.
If you can hear audio getting to the radio, then another
worthwhile test is to try 5-10 watts output. This will use the
low power amplifier in the radio, skipping the 100W amp.
Good luck - Bill, AE6JV

I have tried test mode everything looks normal in test mode.
When not in test tried with wsjt-x through a signal link as I
had been using it for months on 1o,12,15,17,20,and 40 meters. I
was using it and everything was fine. Until about 10:00
yesterday. Checked so cables between te radio and amp. Then I
realized I did not have even the drive to the amp. Absolutely
0 watts. I was driving the amp with about 8 watts. Then I
decided to make sure nothing external was affecting the radio
so I disconnected everything except power and antenna cable
to wattmeter and dummy. Still zero. When you depress the XMIT
button on the radio it switches automatically to CW and
transmits a carrier normally. It switches to cw but still no
RF out . Displays dashes for SWR and 0 watts. Hooked a mike up
changed settings. I can see the ALC change but still nothing
out. Tried high power a day low so it is in the drive I
believe as the 100 watt amp is the same results as the 10 watt.

Just to cover the bases, make sure you're not in transmit test mode.

Yesterday I was running some FT8 on 17 meters. All of a sudden
I noticed there was no output out of the amplifier. Then looked
at the radio it had the red XMIT light on and two dash marks in
place of SWR and said 0 Watts out. So disconnected every thing
except power and antenna switched antenna switch to dummy and
get the same thing on any band. Of course when you depress The
XMIT button it switches to CW. But I did hook a Mic up. With
the mic hooked up I got the red XMIT led with ALC on the
display I would see the ALC change as I was talking in the MIC.
But when I switch over to the display that shows RF out there
is no indication of RF. Is this something other people have
had. I realize it could most likely be multiple different thing
but would these indications narrow it down to a section of the
radio like maybe the 100 watt amp. Or something like that.
Thanks for all advice in advance
