reverse light switch, high resistance and leaks, why? Options

[davesprinkle]

OK, I'm now on my third reverse switch, with a consistent problem:

After a few hundred miles, the switch contacts become high-resistance (50 Ohms or so) and the switch leaks tranny fluid, filling up the wiring boot. By the way, the last two switches were brand-new Porsche replacements. I'm running Swepco 201, by the way. Anybody have any suggestions about what might be going on?

You are correct in what you post about the more resistance the less current. I am just going by experience in 12 vdc auto wiring. When a loose connection happens (more resistance), heat builds up and the connection will fail. I'm kinda old and we went from tube tech. to transistors and had to reverse flow of electrons in the 60's but I think I remember if a loose connection happens in a circuit the amperage would go up and create heat in that connection and continue until it burns enough to open up completely. Black or dark blue brass connectors in a auto connection are good places to investigate problems.
