The switch I have on my 52 only has two positions on or off so all three terminals are the same on mine, with foot start there is no [censored].position at lest on my switch I would quess because the foot switch to start is seperate so any time you turn the switch on it's only to start the engine every thing else works all the time,lights,heat fan,etc and is not conected to the switch. The only two things that the switch turns on are the coil and the gas gauge.
