How to get to the fuse box on a 1984 Honda magna?

Recently bought a 1984 Honda magna when I first got it my buddy helped me jumped it it started then died I told him put the cables back on but he put the positive and negative cables backwards on my bike so not even jumping it will work i was told it might be a blown fuse but I have no idea where it is any help would be awesome thanks guys

I don't know either but a common location is either under the seat or beneath the panels on the sides of the bike right below the seat. I'd almost bet if you googled it you could find an owners manual online.
