I have an SNES Controller where nothing works. I tried cleaning it out with q-tips and rubbing alcohol and still nothing. I am now assuming that there's a break in the cord. I don't know how to tell where the break is in the cord; as I do not want to strip the whole cord for nothing. How can I tell if there is a break in the cord and where it is located before I have to strip the cord's insulation? I really want to get this SNES Controller working again! Thank you and have a nice day.
