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

Battery new or old (fluid levels), Charging System and Components, fuses, wiring harnesses, and look for loose or bare wires including lights and wires...good luck this will take some time but worth it in the pocket book.

Not always necessary to change the regulator/rectifier. Check all connections to make sure they are clean, use a good contact cleaner and finish off with dielectric grease on your electrical connections.
When some bikes get a few years on them the connections get dirty. Check to see if there are any burned or discolored wires anywhere around the regulator. The FIX on some bikes is to cut the connector completely out and solder the wires together and either seal them with heat shrink of a good electrical tape. Loose or bad connections get hot. As long as the regulator and rectifier are working there is no need to replace them if the connections are good.

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.
