Oh, BTW... The black wire is not a ground. It is spliced off the brown wire feeding the marker lamps in the hood. It's a wonder I didn't blow a fuse when I grounded it. Also, what the schematic shows as a brown wire to the front park lamps is really white.

I'll have to track it down, but my knee jerk reflex is to go straight to the turn switch assembly.

I did fix the headlights: given the overall condition of the van, I expected the bulbs were bad, and I scored a full set plus spares for $20. Unfortunately, it turned out to be a cut hi beam wire at the hi beam switch.

Anyone need a headlight?
