OK, I found the yellow wire connector, and it's all looking good, thanks.
Now, am I being thick, or having a blonde moment, or did I simply miss something? Looking at the two main circuits at the famous red plug, the red wire (power to fusebox) and the red/white wire (charge from alternator) are connected inside the starter relay, before the main 30A fuse. So, if you're riding along and the main fuse fails, then the bike simply keeps running on the voltage coming from the alternator. The fuse may have blown because of a short between the starter relay and the fusebox, but the alternator will keep charging (probably flat out) until something else fails.
And that "something" is likely to be either the wiring, or the diodes in the rectifier, either one of which is an expensive fix.
So what exactly is that 30A fuse protecting?
I would love to hear the experts' opinions.
