Congratulations on using such a fine grit paper. THAT was important. And I suspect you know it. Many folk think they can just file or sand ANY contacts to bring them back to life. And, of course, they do revive . . . . for a week or two. What people often don't realize is that by filing contacts they have enormously increased the surface-to-air ratio of the contacts. Perhaps hundreds fold or more. This promotes rapid oxidation, i.e. rust. That's shortly followed by even worse contact resistance. The best solution is to use a "burnishing" tool or apply that contact cleaner to a strip of paper or very thin leather and draw it repeatedly back and forth between the closed contacts. You'll wind up with clean contacts without developing the extra surface area that promotes rust and even worse problems than you started with. Regards, Warren Good point on the contact cleaner and a piece of paper. When cleaning points on a point type ignition on a snowmobile, it would do the same thing if you filed the points. Piece of paper and some contact or brake cleaner does the trick. Spence
