On the cut-out switches I have seen the smaller terminals are used just to earth the alterrnator via a chunky resistor to stop it going overvoltage should someone operate the cut-out switch when the engine is running. Is yours different?

PS - if you haven't already got one an automotive multimeter - or even a bulb fitted with some flying leads and croc clips - is pretty essential to debug the wiring. Even if you do know what you are doing!
