I understand, people add in line fuses because fusible links aren’t as easy to find and they tend to be a little more expensive. Plus, it’s easier to replace a fuse than it is a complete fusible link wire. Regardless, I don’t believe the inline fuse is the problem compared to using a fusible link. Something isnt wired correctly or a wire is touching something it shouldn’t be. It has to be on the ignition circuit.
