Fuse Hot To Touch
« on: September 23, 2018, 10:39:58 AM »
Hey i have a 1973 cb350f with a single fuse system on it. The bike started going through fuses once a month since may. When it first blew a fuse, the hi-low beam light switch broke (the plastic inside the switch cracked in half making the switch inoperable).

I went for a ride yesterday, turned the ignition on and no power. I checked the fuse and it was blown. I put a new fuse in and turned the ignition to make sure the power worked. The power worked but the fuse was very hot to the touch. I am thin king the fuse shouldn’t be hot. Is this correct? If the fuse is hot does it mean that there is a short somewhere in the bike?

take the handle bar control that houses the hi/low switch apart and see what's what.
