Hi William my name is ***** ***** I get the current mileage on your bike and also do you have access to a multi-meter ?

Hi kenny o. yes have a multimeter. I am an electrician by trade2. i checked the stator output at rectifer plug. making 27 volts at idle then goes up to 65. dont know how to check the rectifier out put. i installed a new rectifier but still only 12.2 volts at battery. milage on bike is 15,000.

OK good, thanks for getting back William, lets first try getting some AC reading out of the stator "under a load" the three wires coming from the stator where they connect to the "main" harness or you can check it at the regulator/rectifier. What you want to do is get a VAC reading with everything hooked up (loaded) so start the engine and then measure across the three wire, do this at idle and you should be seeing anywhere from 11-12 VAC, if it its higher that's OK, if and when you probe across one phase and its below what would be 11-12 VAC, then that is an indication that you likely have that phase out (shorted) and would require stator replacement, now do this reving up to (loaded) this will test for a layer short across the windings on the stator.

Let me know what you come up with, or you have any questions

Thanks William
