...The line to the headlight (at the headlight) seems to be dead now for some reason...Could the resistor have blown .  I tried to hot wire from the male plug leading from the tender directly to the headlight and the light flashed on then everything seemed to go dead.  The generator sound is there when I choose forward on the NCE handheld but there is no light.  Right now the engine runs fine and I have all the other functions....bell-whisle-horn-etc....The tech at Bachmann said I may have to default and re-assign the engine # to get power back to that line?

Recently bought an outside frame 0n30 consolidation and when I unplugged the two prong plug from beneath the cab the female portion pulled off the circuit board.  It seemed the other two prong plug on the board lead to the headlight so I unplugged that from the board and hard wired it to the one from the tender and the loco would not run.  It now seems the wires at the headlight are dead.  Any suggestions on how to troubleshoot and repair......Also...how can I check to be sure that the headlight is not burned out?
