I found some 5x25mm glass fuses on Ebay, Germany some years ago.
I ordered some 5 packs of 7A, 15A. Maybe 10A too.
5A not available then.
Good to keep stock fuse boxes when they work.
Both my bikes have relays fed by thicker wires direct from battery with hanging 10A mini fuses to make life easier for ign switch and bar switches. Hi, Lo, ignition.
