Fried something electrical, please help

I work out of town often, so i do not get to tinker with many things. But long story short, after I used the seafoam soak to free my 1992 fzr 600 carb float, and realize that an overfilled crankcase can slurp motor oil into the airbox, I finally get to ride. But a few days later, my engine would die occasionally during a slow moving right turn. I knew I had no killswitch, and the gas was full enough, so I guessed a loose wire. So I parked it, took a break, then came back. Did what anyone would have done and turned the wheel to the right with the ignition on while in neutral. And as I expected, the neutral light went off, then back on when I centered the wheel. So I looked for any bunch of wires to gain tension as I moved the handle bar from right to center and found that the ignition cluster would pull tight as I did so. So as I looked it over, I located the metal keeper tabs that bite the wire cluster behind the ignition switch, and found that it bit one of the red wires in half. So I felt relief knowing that this will fix the problem. So out comes the trusty pocket knife and I begin to do the wire splice with electrical tape. But during this, I let go of the battery side of the splice, and wham, it arcs off, and welds itself to the frame. So now, since i did not disconnect the battery, I have now fried something in my electrical loop, and am not one that is endowed with electrical smarts. So anyhow, I checked the fuses under the seat, and none of them are blown, and as you know, the ignition will not come on even if I hold the wires together. Any suggestions on what part would suffer under these circumstances? I do own a repair manual for this bike, but it has no reference for stupid mistakes. Hate to throw hundred dollar parts at this, but The only thing I can think of by looking at the wire diag would be the "STARTER SWITCH ASY" which is located under the seat. Please help, When I get off of this job, I would love to go out now that it is warm outside again.

first check your fuses, if you are lucky, you just popped the main fuse. worst case you fried your digital ignitor, i did this same this with my powerpak, the bike would crank but never start. the only way to diagnose that is to rule everything else out first. so first, fuses, because you have no power at all, then test your battery and VR.

Sounds clear now that I think about how you referenced it. Start at the battery, then work my way through the loop. Once I do get a chance to dig in, I will make the effort to thank you, and share the end of the story one way or another.
