Well, when I went out this morning I checked the voltage after starting it up and it was at 16V. I hopped in and took off and the light was on brighter than ever. Dim at idle but full brightness around 1500rpm. A little later in my drive I got on the pedal and when it reached about 4500 rpm the light went out. It still hasn't returned yet. I will take some more voltage measurments this evening to see if maybe it has calmed down.
