SOURCE: stator wiring overhaeting
My 96 GSXR was doing this too. I found I had oil leaking into the stator case. This had "washed" the insulation off the windings (I think) causing it to short out. It shorts worst when it is hot. Now when I disconnect the generator while running it runs great. Reconnect, and a huge blue spark arcs across the plug. This causes a huge current flow at this plug (back and forth). I haven't gotten all my parts yet to try out my diag. Check under your stator cover, or just continuity test it in the bike (OHMs meter).

I have a '07 C90T.
I have just replaced my stator. I replaced the reg/rectifier earlier this year. I replaced the battery one year ago in October.
I firmly believe what started the problem. Two guys that I told I didn't need help, but they pressured me to let them help. They hooked a battery backwards to my bike. A lot of people believe that's what shortened the life of the rectifier and stator.
But keep this in mind. The connections for the regulator/rectifier are not waterproof. I had done a lot of rainy riding and I first found a burnt connector on the discharge side of the reg/rect. My mechanic told me I needed to replace the reg/rect so I did but I soldered the wires and made them waterproof. I didn't do this on the stator side of the reg/rect and a few months later, when the bike quit charging again, I found that connector burnt, so I cut it out and soldered and waterproofed it.
Two days after we got back from a 700 mile round trip to Red River, NM, my bike quit charging again. This time though, I have a voltage meter on the bike, so I was aware of the problem before the bike could strand me someplace. Get one of those btw.
When I checked the old stator after I replaced it, I found the stator good but the pulse signal generator bad. It's required that you replace both btw. You have to, they are joined at the grommet.
Ok well, the battery cost $60 last year and I replaced it myself.
The reg/rect cost $140 through my mechanic and I replaced it myself.
Got the stator online for $173 shipped and they advertise a better stator that puts out 20% more power.
Not counting little things like solder, tape, heatshrink and such, I'm out a little less than $375 on my charging system.
I hope it's a done deal.
Again, some think the problems began when the battery was hooked up wrong, but I lean to believe the sub-standard Suzuki connections may have a hand in this.
Hope this helps. . . Joe

Start with the basics. Check the fuses, then use a digital multi meter to check continuity from the fuse panel to the fuel pump and coils. If you have good power/ground/continuity, the next step is locating a complete wiring diagram to find out what other components are in the loop. But if you start with the basics first, you won't be dropping hundreds in parts for a $.12 fuse.
