So to the multiple questions... it doesn't say 12v on the fuse, but the bike was working with it, and it looks original (based on documentations), holding on each sides with the screws...
For the ground wire, point taken. I'll check it out next. A side wire also makes the ground (a battery maintenance connector was added), but I'll check both saturday morning. Just one more thing to triple check : there are 4 fuses on the front, one flat fuse next to the battery, and that's it.... right ?! Also, does anyone knows by heart what connectors from within the light case I should reconnect to have some sign of life if I have the ignition on and put my finger on the right issue ?! (like putting a turning signal on the front and making sure it is connected in the light... I'll look through the electrical chart to find where the 12v arrives in the fuse panel... at least if I have power coming in, I know the wiring between the battery and the panel is correct. Then I'll go back to inspecting each plug in the back of the panel... ... long week-end ahead !
