just got a free bike from a coworker. its an older peugeot. its in great condition, but he removed the fenders, dynamo, and lights. it has teh wiring ran through the bike, but he clipped the wires at the ends. it has a wire for a headlight, and taillight. but i dont understand whats going on haha.
THose things use one wire for power, and the frame of the bike for the other wire - the ground. WHen you put it back on, there's a little screw in the bracket that digs thru the paint to ground the circuit. Make sure you use that. Other than that, just run wires from the generator bottom clip to the two lights. Can't hook it up wrong!
