Hi there
Hubby had the same problem. In order to diagnose properly you need to recharge the battery then start the bike and run it at ~5000rpm with the plugs connected. Pins B1, B2, and B3 are the output from the alternator and will be in AC volts, around 50 or thereabouts. The wires BR and BW are the outputs from the rectifier to the battery. They should read 14.8V or thereabouts. If it is very low or non existent then the rectifier is cactus. If you are missing one leg of the AC supply then the alternator is cactus.
We have been there and done that.......on the side of the road at last years Snowy Ride!!!
