I have a Suzuki Katana GSX600F. So, after an accident I was in, I rode the bike home and all was fine except a little cosmetic damage, then in a rainstorm it tipped over and after picking it up and trying to fire it up, it started smoking slightly, so I turned it off and removed the gas tank, and noticed a wire was split and burnt. I replaced the wire, got it all put back together, and now the lights all come on and stuff, but does nothing when I push the start button. I’ve checked all the fuses and they are fine. I’m not sure where to go from here.
Start from the beginning. Check your battery. Then check your fried cables. Try to fix as much as possible. Make sure nothing is short-circuited.
If all looks good, pull out the electric wiring diagram and identify all the items which prevents it from starting. Measure all these points and make sure there is no short/open circuits. The obvious would be: side stand and emergency break switch.
The previous would be first items you can check. If all of this fails, you will have to dig deeper. Anyway, this would get you started...
