When adding up how many amps maximum might flow, in order to work out the fuse rating, do I need to include anything for the ignition coil? Otherwise I guess its just headlight, tail light, stop light, speedo light (horn is on another circuit). My bike is a 1965 B40F and I'm thinking the amps add up to just under 10, so I guess a 15 amp fuse would be okay. I note however that AWJDT says 17.5A is suitable for many classic bikes, having a blow rating of about 35A. So maybe that would be more appropriate? Also, I believe glass fuses have both the continuous and the blow ratings marked on them, to avoid confusion? Phil (novice)
