I was working on my 1976 Williams Blue Chip for the past 2 weeks. I had a couple problems that had myself and people trying to help me from the forum chasing our tails. I figured it out last night- the armature plates are magnetized and not releasing which was causing different intermittent problems. I put a piece of electrical tape on the armature plate and it fixed one of the problems, but the other one- ball count unit problem, sometimes works properly, sometimes on reset it cause that relay and others to "chatter" and not engage properly and then other times the armature sticks giving me my original problem.

Is there a way to demagnitize these, buy new ones, or use something other than electrical tape that I'm currently using?

I'm not 100% sure they are magnetized, I just know they are sticking. Is there a way to tell if they are magnetized or not?

I can test it tonight with some metallic like you mentioned.

It would probably melt the plastic piece the switch blades go in unless I drilled out the rivet and re-riveted it.

Cool! What is the soldering gun method?

That makes sense. What is the best way to get them off, pull the switch stack?

Ok, I was wondering how to do it and how it worked.

I can check this, how are they supposed to be magnetically insulated from the frame?

Ok, will do.
