John what has been your experience with a defective AC regulator?
I recently had to get another two from Lionel due to one crapping out again, the engine also happens to be a TMCC J class (6-38095). I put a new regulator in the engine, an 8 ohm resistor in the smoke unit, and when power is applied to the track the regulator shorts. Checked all wires, connections are secure and not touching each other or metal.
