i have been restoring a series one for the last three years. Ive got to the stage of trying to get her running, but i have no spark. its got power to the coil via the black wire. my suspicion is with the green wire to the coil. it has a constant voltage to it of around 9 volts even when the distributer is being turned. also if any one knows what voltage reading i should be getting at the wires going into the distributer. thanks for any one who can help
