There should be direct contact between the indicated points, so you should see close to 0 ohms (1-2 ohms would also be fine, but no higher than that).

Desoldering braid needs a proper temperature before it will work - higher than what is needed to simply melt the solder, and your iron is simply not beefy enough to heat it up.
