[Elecraft] do I miss something...?

[f9oj.7]

Hello
I assembled a W2 wattmeter last december, but I had to spend a couple of 
weeks in a clinic, and when back home, I tested it, but it did work as it 
ought to !

When "power" on, no problem ; when tapping"range", the 2 watt led never 
lights up. The others do normally.

If I apply RF via the K3, the whole line of the "power" green leds lights 
up, whatever  power applied, and the SWR line flickers all over the range.

Has anyone an idea?

Thanks for any suggestion.
