When I (last) repaired the electrics on my bike I considered moving the fuses and using a waterproof fuse board. I never did it, but probably should have. I calculated the maximum current draw using the wiring diagram (same as scaly posted only less colourful) and although I dont have my scribbles here, I am sure it was about 14A max. Headlamp on full beam (60W so 5A), indicators on (were 23W so 2A each, total 4A - but are now back to 10W), all the wee speedo lights (fuel, mil, speedo, indicator, fb and neutral tell tales = 12W total, so 1A), tail and stop lamp (I think 50W total? So 4A). Total on the lighting circuit is 14A give or take a bit, and that is if they are all in parallel on the same fused circuit. So a 15A fuse should just work out, 20 A allows wiggle room. However, that doesnt count for all the shorts-to-frame that exist!!!!! EG tail light wiring loom, main beam connector via speedo cable, shorting tail light due to water ingress, ditto indicators and the ridiculously close battery positive terminal, solenoid feed off and frame.
