I noticed today that my gauges/tail lights were not working on my 2013 GL1800. I checked the fuse (20A) and it was blown. I replaced it and within seconds of switching the bike on, it blows again. I've added nothing new. I do not get sparks when I replace the fuse with the power off so I don't think I would have a direct short to ground. I am guessing a pinched wire. I was wondering if anyone has a general idea where I should start looking? Thanks.
