Thanks Eric. I'll try the dialectric. The pin is already adjusted about as far as it will go.
A point of clarification though. My electical contacts are the same as yours. What I'm referring to is the hole where the locking pin goes in. There is a switch in or next to that hole that won't send power to the contact pins until the pin is inserted. When I was playing with it today, it appeared that the pin is magnetic and the switch is a magnet activated reed switch...either that or an awefully quet and smooth micro switch.
Thanks again about mentioning the dialectric, I forgot about that toward the end when my toes felt darn near frozen.
