went out the other day and while cruising through town, the radio turned off and when i looked down, i noticed voltage was at 16+. completly pegged. I pulled over and radio came back on, voltage normal. I continued on and then battery light and check engine light came on. Voltage at 11ish. Any ideas which part of my charging system is causing this. My suspisions are VR, but not positive. Bike is an '11 FLTRX w/ 26k.
