Why would the glasss fuse blow? (What's the amp rating on the fuse, btw?)
It took all my lights with it. Now, whenever I replace the fuse and turn on the lights, the fuse blows instantly. I haven't done any wiring work at all. Not sure if this means a bare wire is shorting against metal somewhere.
I can't ride at night without lights. WHy would that fuse blow so quickly?
