If you can - measuring from the two point back at the SWR card - FWD and REF -

Remove the 2 wires going to the pot on the front of the board, but keep ground...to it...

Then re-measure at those two points to eliminate the switch causing this issue.

If it still shows a resistance (not open) - then the card and the parts on it need to be checked.

Be extremely careful with the card, those traces have been there since the beginning - it can tear open or lift on you...
