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

What I learned on my '07 C90T----- is if it doesn't charge, it doesn't run for long.
I bet it's the battery.
I've had charging problems and I do blame a portion of it on Suzuki's connectors at the regulator/rectifier not being weatherproof.
I had to replace my battery at less than 10000 miles.
I had to replace the regulator/rectifier last April.
I had to replace the stator just two weeks ago.
When troubleshooting, I disconnected the stator at the reg/rect and only got 40 volts at high rpm.
It's supposed to put out 80 volts.
Got the stator from regulatorrectifier.com for half what the Suzuki shop wanted. Paid $173 shipped.

The site below (exploded views - part chart) should get you mobile again, see electrical and wiring harness sections . The rest of the bike is there also. Cheers.

the stator is behind the front cover on KS side, must drain oil and will need new gasket, normally when it burns out it takes the rectifier/regulator with it!!
Recommend Ricks Stators on line this is a better replace ment than OEM, mine has lasted 2 1/2 years so far (this was third replacement) Also recommend relocating the regulator to the bottom front of the battery box (requires fab a plate and extending wires and solder connections) this allows it to get more air and stay cooler I also added additional grounds
