I have had an accessory fuse block wired into the FJR for several months, but have had it more or less tossed into the cavity under the seat while I puzzled out where to mount it permanently. One tempting location was hard against the rear subframe, where it could occupy space that remained with the pillion in place. Installing the box there would satisfy my requirement of fuses within easy reach, but the subframe crosses the taillight assembly with bare accommodation for fat fingers to reach through to the sockets, and my determination to ensure the brake and turn signal bulbs were accessible for roadside replacement on dark and stormy nights complicated devising a solution. Banging up my knee this summer gave me something else to do for a while, but finally this weekend I had time to play with my scissors and paste.
In addition to the two that can be seen in the photo, there is a pair of thin, parallel vertical spines in the center of the subframe assembly supporting the tail covers, with a gap between them of slightly less than an inch. From outside edge to outside edge, the span is 1¼". I cut a piece of aluminum stock to that width and covered what would become the back side with a thin rubber sheet to dampen vibration. I formed a hook on one end of the aluminum strip to grab the bottom edge of the subframe, then, having aligned the strip to the edges of the spines and shaped it to their geometry, attached its top edge beneath the tail covers. A bit of Velcro affixed to the exposed side of the fabricated bracket holds the box neatly into place, which can be removed instantly if I need to replace one of the light bulbs on either side, and otherwise presents its cover for painless inspection of the fuses within.
