In the process of Dual-Sporting an '02 XR650R. I installed a regulator/rectifier purchased from Ricky Stator, first wiring it into the stock wiring lighting coil. I also plugged in a new 12 volt sealed battery. When I fired it up, I found that voltage would rise with the engine RPM, but would just break 12.5 volts, not enought to keep the battery charged. I have since re-wound the lighting coil, wrapping all 10 poles with 18 gauge copper magnet wire. This has increased the voltage output, but it still just touches 13 volts at high RPM, even though I'm still using a 35 watt headlight and standard tailight (nothing else is drawing off the system). I still fear that the battery will go flat, plus I was hoping to use a higher wattage headlight. Any ideas as to why I'm getting such a low output?? Thanks in advance!
