Thanks for all your replies, I'll try to take them in order.
BRUK, I checked all the plugs and wires, everything looked good.
HANCOCK 52, If I can get the pictures up there is one of just the male plug that I disconnected then connected to the red and black wires of that plug, when track power was on (whatever voltage) it was constant, I think it was AC voltage. Although the resistor looks bad it still measured 6 Ohms.
GUNRUNNERJOHN (like the name), I hope I can get the pictures up for you, it's such a nice engine I would really like it to smoke.
Thanks again.
