Voltage for Model Power 3 light signal?

tired powering it from my DCC main line, and didn't light, then the power supply for the building lights, nothing, then then turnout power supply and it finally lit up nice and bright, but the resistor on the switch got pretty hot! It does not say the voltage on the box for the signal, anybody know what it should run at??

Help!
