Luckily, this "project" is with my pal and prior partner, not me. The owner brought this car into our shop two decades ago for a service, oil change, etc. Reportedly he'd bought it from someone in France. Never mentioned electrical problems... hasn't been on the road in 16 years. Turn signals work unless the headlights are turned on. Then the turn signal circuit is powered constantly. We're thinkin' some Frenchman did some "creative" wiring to make the two bulbs "extra tail lighting" after dark. We have the schematics for these cars and my pal says there are a LOT of wires in there that don't match the map. Ugly.
