hey guys looking for some help. I have a 1976 CB550 that my dad bought brand new ,he has since signed it over to me .I have put around 5000 flawless miles on in until last summer I started with an electrical issue . while riding the bike the main fuse would get very hot to the point the fuse block started to melt and of course the fuse would blow . Any input on what the problem is would be greatly appreciated !!!!!!!!
