Just had this exact problem with my XS400, the main fuse was heating up and melting the plastic without blowing 🤣 ... a simple blade fuse ebay replacement and one less problem 😎
I know this is an older video but I recently purchased one of these as a project bike and it didn’t cross my mind when I bought it but the dude who I bought it from took it out and I’m thinking that’s why it has no spark, could that be it?
Need to do this with my XJ650 soon. The previous owner made a mess under the seat and most wires are joined with wire nuts. There has to be a similar style fuse box that fits under the seat though right?
I'm not sure if you ever got it figured out but I bought an xj750 with the exact same issue. Previous owner wired everything with wire nuts and it's a mess
Generic blade fuse boxes from ebay/ Amazon will do fine. They are cheap but effective as the parts and materials are so basic. It just depends how many connectors you need and the dimensions you require. It's an very easy fix but time consuming. As for the benefits, I'd recommend it as the old Yamaha boxes get very hot, corroded and have high resistance. You'll get brighter lights and less current draw. I'd recommend it 👍
