I need some advice fellow visionaries...I have a '12 VV with 25k miles. The other morning I took a ride to get some air before it got too hot here in South Jersey. I stopped for a cup and when I pulled away my battery light came on.
I was reading only about 13 volts even at speed and it was steadily dropping. At one point I had to stop at a light and it began charging briefly but that was short lived. I pointed her home but after about 10 miles I was down under 10 volts and sinking, she started missing and died.
Progressive Ins. roadside assistance my *ss but I did get her home in one piece eventually.
I read what I could find on these forums (incredible amount of info over the years) and was pretty sure the stator was fried so I charged the battery and tested the output per the Service Manual (free download thanks again vision-riders). The stator is supplying good voltage, right at 25 volts at idle give or take a decimal and consistent across all three poles.
I'm thinking the regulator may be suspect but the testing procedure isn't all that straight forward to me...diode testing? What, what?
