Default Re: sturmey archer front dynamo debaucle?!

If it has a single wire coming from the dynamo the frame is the ground but you'll have to check with a meter to see if ground is positive or negative.

My tail light clamps to the seat stay and it has a set screw in the clamp to dig through the paint and get a good ground.
