Yeah in my internet research I can't really find anything that specifically says there is a fusible link / dogbone fuse on the bike, I did find one site that is selling them for 78 K8/SS but no specific literature. I did find a full wire diagram which helps because there is no original headlight bucket that tells what wire is what for the lights. The guy who had it before me was attempting to attach a dollar star Harley wanna be headlight bucket which I'm going to use to hold loose bolts or a plant, cause its just that horrid. The bike came with a Vette Faring, so somewhere I'm guessing that was installed, and then someone removed it, thus no more original headlight. I'm using the bucket off of the faring since it somewhat matches the original until I can either find an original or something better than the dollar store one that came with it.
The three fuses I knew about, the 15 / 7 / 5 amp right under the left side panel. When I shorted the wire out, it blew the 15 amp main which I replaced but still had no power. I don't see anywhere that there would have been or be a fusible link near the battery, I've traced the battery cable to the starter solenoid, checked inside the solenoid but then there really isn't anything to trace, as the main wire off the solenoid runs into a main whip and then back out into the starter motor. There's two 14 gauge or so wires off the solenoid into another whip.
Either way though I'm going to pick up a test light and start tracing. I'm also going to pull the fuse panel off since the connectors are pretty rusted up and give them a good cleaning. Also got two buddies, one who has experience with Honda wiring coming over to check it out. So hopefully I'll figure it out. Thanks.
