More installments for my model train electric company! Three regulated Power Line Loops each connected by one wire that will accept negative or positive current (test by switching the switch) and the source distributes 3 volts to three 1.5volt lamps (totalling 4.5volts distributed). Switching the switch shows the surge change but the lamps are not phased by it saving fuzes and resets of breakers from the source to the regulators portion circuits.- nforystek
