switches with deoxit, etc. before installing. This time I'm going to remove the old solder and replace with new instead of just melting the old like I did last time.
If you didn't add any new solder during the resoldering, you didn't do it right. It's not so much the new solder that helps, it's the new flux you get with it. Reheating old crystalline oxidized joints is an exercise in futility. -- Jim
