I had considered just getting another dynamo but I don't want the headache at this point. I just spent the last hour trying to get the light to work but I can't get a good ground on this bike anywhere. I tried all over, even places I obviously wouldn't be able to mount a ground wire just to check, but nothing. Yes, the light does work, I pulled it off the bike and used some test leads to check it on my cars battery. I think I'm just going to do the flashlight thing. I might try getting a pair and using the screw on cap at both ends if possible and then drill a hole in one to extend the wires and run them through up to the light on the bike. If that doesn't work, duck, there may be an old bicycle light sailing through the air.
