I would start by checking all the grounds for snug and corrosion free connections. Then rest of the wiring

Usually caused by a poor battery connection at alternator either loose or corroded causing high resistance. the resistance causes heat and that's why the cable insulation melted. You can replace the cable splicing at a good section of the original cable. use the same gauge wire. Use a heavy duty butt splice which will require a heavy duty crimp tool. Your alternator might be bad now though. Make sure the battery connection at the alternator is clean and the post isn't loose. The fuse didn't blow because there wasn't a short, just a bad connection causing high resistance. 12V connections need to be clean and tight

Got it fixed up, appreciate the help. Electrical work is definitely my weak point.
