GBRf66701 Posted April 24, 2019 Share Posted April 24, 2019 I want to add a motor to a roof fan of a Hornby class 56. does anyone know if you can add a small 3 volt motor to the function output of a DCC Decoder? Link to post Share on other sites More sharing options...
NIK Posted April 24, 2019 Share Posted April 24, 2019 Hi, If the motor takes less current than the function output is rated for then you should be able to add a suitable resistor in series to drop the function output down from 12 volts to 3 volts (or lower if the fan runs too fast).
