[Elecraft] New KAT500/KPA500 Setup Questions (Mark WU6R)

[Mark Wheeler]

I'm a new ham...  I just purchased new KPA500 and KAT500 to use with my new K3S/100... following the wiring diagram of the KAT500 manual, page 5, figure 1, I also attached two E850463 cables (ordered from Elecraft), but when I try to transmit into a 1500w dummy load, by following KPA500 manual page 16, I do not get any KPA500 bar graph lights to illuminate as I turn up the K3S power dial from 1 - 30 watts (page 16, step 2), so as a newbie, I cannot figure out what it is I am doing wrong.  

I rechecked all the wiring, and I do get automatic band switching between the K3S and the KA500, but I cannot figure out how I should "apply a few watts of RF drive" while in "operate mode" to get the kPA500 bar graph to start lighting.  I am pressing the "operate/standby" switch and the KPA500 is switching between the two.

Any assistance is appreciated.  Thanks in advance.  I imagine whatever I am overlooking is probably obvious to many...  Thank you.
