all other lights work baseboard, tail lights, flashers , both turn signal left and right work, I even have power at the head lights , leads me to believe there is a ground problem, I have no idea where the head light pic up there ground cause the lights are run in series. Can you tell me where the head lights are grounded. from the Haynes manual it look like through the dimer multi fiction switch but to be honest I have no idea pleas give me some suggestions . thanks
