new to e-z track.  I put together an oval track with a figure eight using standard left and right turnouts.  When power was hooked up I ended up with a track with no power. My grandsons and I were so disappointed when the  trains would not run.  I initially thought that my connector track was bad.  I ordered new connector tracks only to find out by trial and error that the assembled track was  the problem.    Is there an e-z track wiring book out there?
