All fixed. Thanks for the inputs. It was a ground. The turn signal housing was not grounding. So I ran a short wire from the light harness ground screw near the right horn to one of the studs that attaches the housing to the bracket. Works fine now. I kept thinking it might be a ground, but if the ground was bad, why would it work in turn signal mode with headlights off?? Oh well, it's fixed. Special thanks to
