Okay, I've looked around but can't find what I'm looking for. Somewhere I saw a reference to a fuse on the fuse block for the accessory circuit and how it can be moved to make it a nonswitched circuit (i.e. always on). I want to make my wife's bike accessory circuit switched so as not to cause battery drain (a previous owner apparently wanted just the opposite).

Which fuse block and fuse is it and how can I tell which position it is in? Thanks.
