I wasnt really concerned. All of them were still making contact. The spares were the ones that had the most corrosion. I am just going through my old is new to me bike are doing things like replacing fuses that look tired. Im doing the same with hoses, radiator fan motor, replacing screws and nuts, putting antisieze on some items that should have had that to begin with, checking torque numbers, etc. It's just for fun, I want her to look and ride like new. I'm not a ride or die guy, its just fun for me. Im not a mechanic so don't beat me up about that...lol If its not broke don't fix it, I get it.If you really are concerned about fuses and their contacts, good or bad, replace them again with the EZ-ID or Smart-Glo kind that will light up when they pop. Makes tracking down a problem so much easier, and they aren't that much more than the regular ones. Readily available at auto parts stores.
