Just got my SD-45 yesterday and nothing but disappointment.  Wish I had read about the problems others had before I bought mine.  The engine stops frequently especially on turnouts.  This is on a layout where 10 other engines from Atlas, Kato and Walthers will run all day without a whimper.  The second problem is the coupler height.  It is too high, about half a coupler higher than any engine or car I have.  This causes the engine to drop the trailing cars whenever it meets the slightest twist or bump.

Any help on the coupler height adjustment?  Based on the comments from owners, with Bachmann recall this engine?
