OK. Searching has shown me that this is a common problem with the XB's. I've done some of the troubleshooting steps. The fuse blows when I have the ignition relay in place. It does not when I remove the relay. I have swapped all the relays around so I'm fairly certain the relay isn't the issue. I've also seen where the #77 connector to the voltage regulator can be removed to diagnose. Which of the connectors down by the front sprocket is the proper connector? It's the one with just the red and black wire, correct? If so, I have disconnected that and the fuses still blow. So I assume that rules out the voltage regulator? Does that just leave me with hunting down a short somewhere?
