The Saga continues... Eureka! The $65 stator works great!!! A 3000rpm the votage at the battery is 14 volts. This increases up t 14.8 or so as the rpms increase to 5000. The fix took only about 10mi to install and now the bike is doing fine. I cannot tell you all tha have offered assistance how much I appreciate it. Thanks so much!!! Jef

Or does the voltage continue to rise? The voltage regulator in an excited field alternator has a large transistor that is supposed to switch the excitation voltage on and off at certain levels. There has to be a reason why the excitation coil in your old stator shorted out. It may be that the voltage regulating part of your RR wasn't working right and the RR kept sending voltage to the exciter coil continuously, burning it out. Also, keep an eye on your battery water, if you have a non-maintenance free battery.
For sure, it's not normal for the Voltage to stay high. After a start, the battery needs to be refilled, so the voltage will rise to 14 volts or more, then after a short time the Voltage should drop to about 12.8 volts. It depends on the condition of the battery of course, this is for a good battery. If the voltage stays high, the battery could be toast, or the regulator is not working. Definitely check it out, or you'll fry more than the alternator. Bulbs don't like voltage that high so if you've been blowing some bulbs, you've definitely got a problem.
