I was undoing the 30 year tape on my harness getting ready to clean it up and tuck it under the fender and found this fusible link with the insulation cracked open. As soon as I touched it, it broke. It’s coming from a grey/yellow wire. Is this link something I can get at the parts store?
Or should I just replace with a fuse?
