Ok, I'm a noob, as I've just purchased my first 2 pins. I'm already experiencing a few problems and was looking into cleaning contacts. I started by reading through the stickies at the top of the forum, followed some links and have a good idea how to proceed.

My question is: How do you tell the difference between contact types? From what I've read, each material type takes a little bit different cleaning.

And that brings up another question, frenchmarky. Gapping. I've read a lot about how it needs to be done, but really didn't pick up on how you know when it's correct.

I've got so much to learn.

Thanks hjh, that makes sense. A bit different than the ice cube relays I deal with in CNC machines.

And now my Space Mission is acting up. Tilted during a game and now it will only score 100's. Just keeps rolling over to all zero's when it reaches 1000. Chimes aren't working on most things either. Things are going downhill fast. Oh well, ordered some tools and will dig into it after they arrive.

BTW, anyone know where I can get schematics for my Space Mission?

You guys are awesome. Thanks HowardR.
