That greatly simplifies things.

According to the wiring diagram, the white wire coming out of the Main fuse goes only to the R/R (so it can charge the battery), the ignition switch (splits into white and white/black at the ignition switch) and the fusebox for the radiator fan. You can pull the Fan fuse and I believe the bike will run without the R/R plugged in. That should help narrow down what area the problem is in.
