The stator puts out AC, at full blast over 3000 RPM. That goes to the R/R, which does two things. It converts the A/C to DC, and it shorts excess current to ground. Make sure the R/R is properly grounded. I've never heard of this problem with a Vulcan before, but I had an '85 Goldwing that actually caught on fire. The R/R could not handle the stator output, got really hot, and set the wires and plastic connector connected to it on fire. These bikes use a Model T charging system. I keep hearing about MOSFET R/Rs, but I've put close to 190,000 miles on 2 Vulcan 750s, and never did replace an R/R. I did have to replace one stator. It was burned to a crisp. I recently bought a 1997 Vulcan with 21,000 miles on it. Before buying it I checked to see if it was charging, and I removed the 3 screw cover to make sure nobody had done any cutting or drilling in there.
