Each yellow gives you an ~70w coil, and the blue is a floated ground (i.e. - the generator output is NOT grounded through the frame). This way you can keep your AC and DC systems separate. So, instead of using a 1-wire regulator that shunts excess voltage to the frame, you'll use a 2-wire regulator that shunts excess voltage back to the blue. If you use something like the Trail Tech regulator/rectifier, connect both SEM yellows to the SAME yellow of the reg/rec, and connect the other yellow of the reg/rec to the SEM blue. Then the red/black of the reg/rec are your DC output to your 12v battery, and you should have a whole lot of DC electricity! Since your AC was NOT run through the frame, you can now use the frame as your DC ground for the battery, lights, horn, blinkers, grip heaters, GPS, whatever you want.
