The only time you shouldn't have voltage between the orange/white and green or between the light blue/white and ground is when the corresponding turn signal is switched on.
Is the main fuse OK? How about the one for the running lights, tail light & instrument lights (the one in the box on the handlebars with the brown/white wire)? Is the cable from the left switch assembly plugged in all the way? Is the battery connected?
If all that stuff is OK try measuring directly across the battery to confirm that the meter is set correctly, then measure from the battery negative to one of the running light wires and again from the green to the running light wire.
If you don't have voltage between the battery negative and the running light wire you have a problem somewhere between the battery positive and the running light wire.
If you have voltage between battery negative and the running light wire but not between the running light wire and the green wire there is a problem in the ground circuit.
