I recently replaced a Lionel ZW transformer that was running my PostWar American Flyer Loop with an American Flyer 17B transformer. Why? Just because.
Even with the control lever pushed to 0 MPH, enough power is still going to the track to prevent the e unit from cycling. I have to lift the control from its locked position to cut power to the tracks, and then re-engage it to cycle the engine's e-unit.
This does not seem right to me - is it? If it is not right, what is the fix?
