I am kicking myself for joining the third gauge layout party because I am back at working on DCC and am having problems again. I am trying to add a head light to an engine with a DH123D Decoder. However I cannot seem to get it to work. The bulb is 12 Volts 50mA, the instructions suggest that anything that has a stronger pull then 50mA needs a 22 ohm 1/4 resistor. I first tried the light without the resistor, the light wouldn't work and for some odd reason the engine would start going backward. The throttle wasn't turned or anything. When I put the resistor on, the engine doesn't move unless I move the throttle, but the light still doesn't work. CV49 is set for a flashing forward light, on one decoder, I then tried a brand new decoder with factory settings and still no result. Does anyone have any ideas as to why this is happening?
