This is the classic challenge of a british bike. It started fine, and ran fine for a while before dying unexpectedly. A quick look at the wiring revealed that it was fried from the rectifier down to the ground on the frame. Why ? I have no idea so far, but it will need a harness. Looks great, but today it required a rescue call and the trailer. I am not ready to eliminate the PO or me from the equation yet, but I have not really touched the wiring. This is how British bikes get their reputation!
