Okay, so there's one wire coming out of the headlight, and one wire coming out of the tail light? Test each by running a 6 v current from the wire to the mounting hole. If the bulb doesn't light up, take it out and test it separately. If it's burned out, replace (replacement bulbs are another story. Anyone know a good source?).
To test the dynamo, set your multimeter for 6 or 12 v alternating current. Use the wire for one terminal, the mounting hole (where it attaches to the frame) for the other. When you spin the little wheel, the meter should jump.
