Just went out . The A side. BUT, this is strange. I can cut the C terminal, on and all is good with the train running
and place the Micrometer, on the A, and get a reading of 9 volts. Only while the C is on and not the D. I am not
knowledgeable at all about these electrical or PW issues, I am a wire it up and hold hands to gether and pray it works.
