I have a Lionel Legacy Blue Comet Pacific (item number 6-11335) that shorts the circuit breaker as soon as power is applied. The tender alone does not short out but the engine alone on the track causes a dead short. I have removed the shell and do not see anything that looks our of place or any pinched wires. The boards look clean and like new. I have tried both with the smoke units on and off but that make no difference.
Any suggestions as to where and how to check further?
Thanks in advance for your suggestions,
