What did I do and how do I fix it? 1953 Mercury

I am not a 51-53 guy nor have I worked on one BUT being that its still 6V positive ground THE best thing you can do IS when you remove any socket, wire connection, make sure you clean them to shinny metal and where they attach to ALSO to shinny metal so you have good solid grounds. I also like to use a swipe of di-electric grease on what ever I clean to make sure that the connection STAYS nice and clean and solid. ALSO make sure any wire you use is the proper size wire for 6V systems, normal auto parts store 12v wire is too small for 6V systems. Good luck, I am sure someone more capable than I will chime in here.
