I just replaced the stator on my bike. Headlight went out. Few hours later, tried to start the bike no go. Couple buddies pushed it and it started. Lasted about 2 miles and died. First time a Honda (nine of them!) ever quit because of a malfunction. Discovered that the connector between the rectifier/regulator and the alternator was almost completely melted. Measured voltage across the battery with engine running and it was less than 12 Volts.
I suggest you pull the stator then remove the support and protection bracket covering the wiring harness inside the casing. When I removed that bracket, the wire harness separated. The wire underneath the bracket was powdered! I now believe that some mods I made may be responsible for the problem. I have a custom undertail and rear hugger. The undertail does allow moisture into the seat and body cover. I am sure that wouldn't be my fault!
I believe the connector was building up resistance over time. I had been in a light rain about 2 weeks prior and a real heavy rain a couple of time in the past 2 months. I checked the regulator and could not find any evidence of heating or other problem although I am not sure that I would be able to tell by a visual inspection.
So, I ordered a stator and just finished installing it. Now getting 13.7 volts across the battery. I am plan on soldering the rectifier/regulator wires to the new stator/alternator wires.
So, either I was responsible for the connector problem or I actually had a Honda part fail. Again, I am certain I wouldn't cause a problem. Pretty certain I created the monster.
One other note, none of my fuses were burned out. Didn't have to replace any of them.
Anyway, your situation may be different. Use this information at your own risk.
