Low Beams dead, Hi Beam Fine?

Hey thanks for all the excellent troubleshooting ideas. This is a car that I picked up to try to interest my son in a father son project. He has now left and joined the US Marines so I am on my own trying to futz around with the Dart. I was hoping that it was not the bulkhead, because that thing is a gaggle of wires, all spray painted black (unknown why). I know a few of those terminals are melty looking , but that is a real old melt. A few years ago I did replace a couple of those Z terminal conectors, but tried to not mess with most of them. I wiggled them around and now the low beams work!!!! I have a bottle of DeOxit, I am thinking of spraying all the bulkhead bits. Might that help?? I do appreciate being taken to task by the elder members of this forum. Unfortunately I am a drummer by trade, which puts my IQ at a pretty low number.

Hey but you can count to 4, 8, 16 right.

Bulkhead is likely to trouble spot. Pretty common. Look at a schematic and find the terminal. Pull the female terminal in the cabin and make sure it is still in good shape tension wise for holding the male terminal. Heat will cause them to loose grip.
