But fortunately it's my upper back that is sore. I spent the night installing a fuse block on my motorcycle. Just finished testing it, and all is good. The reason I installed a fuse block is that I can better control what is installed. The fuse block is wired to the battery with a relay in line. What this does is provide power to 6 of the terminals on the fuse block only if the motorcycle is switched on. (There's also 2 always on circuits.) As I wire up new things to the bike (like a 139 dB Stebel Nautilus air horn soon, eventually a GPS, cell phone charger perhaps), I have a clean place to wire them to. So the big reason I wired it up was for my new electric riding jacket and gloves. Tomorrow I'll be testing them out when I go for a ride!
