After reading this thread, I went out to my bike, removed the seat and rear cowl to look at my r/r. First, I measured the voltage at the battery, which was good. I started the bike up and the voltage went up to 14 and change volts. Good.
I disconnected the battery and the plug at the r/r. The plug was an off white color...no burning, fattened, or charcoal wires. If you looked at the r/r in the attachment, mine was the color of the right side of the burned unit. Just an off white color.
Years ago, I had an 83 V65 Magna which left me stranded on the highway. I called a friend, took the battery out, went back to my place to charge it, put it back on the bike, and rode the bike back home. All the while, it was losing power. I check the r/r and it was burnt. $200 for the r/r and $60 for a new battery, I was riding again. At the time, the Magna only had 18,000 miles on it. My 97 XX has just under 61,000 on it and the r/r and battery, (yes...original) still look good.
Great Day!

P.S. I wonder if the r/r from the Magna will work? It has cooling fins on it,
the same 5 wire connector, but an extra connector w/3 wires.
