My motor was decked so the numbers were removed but can still see faint letters and numbers just cant make them out. I have used a magnifying glass and still cant make them out. I also have use some stuff called Rag100 from a company called Sirchie still havent been able to bring them back. If anybody has a solution PLEASE HELP

Try heating the pad area, very slightly, with a torch. Sometimes this will make the characters readable.
