Rick, Seeing I have a few years on you, how about this.
Back when the air-cools were new, most of the electrical gremlins were caused ,not by coroded wires or connections, but by, get this, PAINT. To much dang paint. We would have to scrap paint off to get a good ground.
This is the Gods truth. We had new cars to lose wheels while driving along due to too much PAINT. VW never was bashful about paint in the early days. Brake drums really got a double shot of thick black paint. When the car went through Dealer Prep , you always torque the lug nuts. When the 4-lug rim came out was when the problem began. Wheels started to either fall off or loosen up on the drum and the poor old Tech was blamed for not torquing the lug nuts. We took a brand new '68 Bug out of stock , Torque the lug nuts and went on a little trip around the town, up and down Mtns, speed humps, chuck holes etc. Got back to the shop and just about could take the lug nuts off with your fingers.
It turned out the paint on the drums melted due to heat from braking. Since we torquing on thick paint and not metal , the lugs loosened up. We sanded the paint off and no more problems. We alerted VWoA with what we found and from then on ,the new cars came with non-painted drums.
I think this was time that VW started to use less paint behind panels and the rust and corroded period started and is still with us to this day, but at least the wheels don't fall off anymore.
