This is on the 05 that you had the coil problems with? Is the rectifier bad now? With the electrical problems that you have had, I suspect there is more than a charging issue. What is the history of the bike? Also, did you replace the stator with a stock unit or the larger one? Any other electrical issues currently? Lights, gauges, etc? I would check the fuse panel under the left side inner and the main fuse under the seat on the left side and see if the correct fuses (sizes) are in place... Also, I would check all the wiring from the stator to ensure that there are no intermittent connections or cut wires/shorts...
