[T3] Non-Working Headlight

I used copper grease on a Jetta starter wire that had become corroded.  I
cleaned the wire and terminal, and put on a thin coating of copper grease.
Worked fine for a week, then simply wouldn't pass the current.  When I
cleaned it off again and reassembled without the copper grease it worked
fine again, and continued to do so.  I've never trusted copper brease for
electrical connections since - you'd think it would be better than normal
grease, not worse!  I also used a smear on spark plug threads for some
years, but often got some misfiring after, and didn't connect the two.  I
use a drop of oil on the threads instead, and don't get problems any more.

No, we're not after an insulator here. We just want something that might
keep moisture out and retard corrosion. We want the bare metal surfaces to
touch and not form an insulating oxide layer.
