Just to clarify: disconnect the yellow wires from the rest of the harness and measure the AC voltage at that point (engine running--obviously). You have NOTHING? There's your problem--stator is cooked. Or you can do an Ohm test through the same two wires (engine off). Totally open circuit is bad (my guess). Also: you can check either of those wires to ground. That reading should be totally open (no conductivity). If it shows any connection at all, that also points to a problem (short). It's almost always the stator, though on my 1986 Gold Wing, it would cook the regulator-rectifier first, then that would damage the stator shortly thereafter. Did a bunch of those in 190K miles. Around 120K I moved the reg-rect out from under the bodywork and out into the airstream. It never burned another regulator, though stators continued to expire every 30K.
