Alan..you don't say, but I'll guess: You want to wire the turntable's bridge track so that the polarity stays 'right' no matter which end of the bridge (zero or 189 degrees) is at the track you'r travelling to. The way most TT's do this is to have the ring rail in the pit cut into 2 half-circles, insulated from each other. The turntable's bridge has a pickup under each end, to ride on the ring rail.(like a track wiper) Wire from each wiper to ONE rail on the bridge track. The GAP in the ring rail shoudl be placed at about 90 degrees to where the ends of the bridge are for most operation - you don't want it right under where the end of the bridge will be when you're lined up with a track. <br />
