CB750SC main fuse blowing
« on: September 16, 2009, 07:48:41 AM »
Hey Guys, I know this is not a SOHC bike but maybe something will ring a bell with my issue! I have a 1982 CB750 that blows the 30 amp main fuse under the left side cover as soon as I turn the ignition switch on. I really haven't checked anything yet but I was going to remove the fuses between the handlebars one at a time to try to isolate the cicuit that's at fault. I have a wiring diagram but it's really small and hard to read! Does that sound logical? Suggestions would be awesome!  Thanks

Sounds like it's between the main fuse and the fuse panel.  Take a good look for wires rubbed through or pinched.

test the switch itself too for internal shorts
