my gtb is definatly open, it has the leaf under the bottom of the rail and the ball rolls over it to close it, not at the end like my bally machine,
Dunno then, my sys1s must be unique. Seriously, normally closed is how it is.
well wouldnt matter any ways, its easy to enough to look at how its setup if its like your setup or like mine, but as every one is saying it more than likely the switches or wires just test them and see.
maybe mine has been modded who knows
