I am working on this electrical project for my SV, with some minor modifications. Basically, I want a power source off the bike that's not hot when the bike isn't running. My grip heaters are always hot, and I forgot to turn them off one day and ran the battery down. I hope to take care of that problem, and also add an accessory outlet for a GPS as well as a connection for a heated jacket.
What I'm wondering about from this chap's plans is, if I'm using a 12V/30A relay, and the line fuse is 15A, wouldn't a lower amp relay also work? I'm afraid I don't understand enough about the relay to know what matters and what doesn't.
