Ty for your answer sorry about the lack of info. Either way i figured out the problem using a meter. The E-Z track n scale switches had some major resistance problems so I took them apart and tightened some things and poof 3 out of 4 now work perfectly. One was originally backwards so that when the frog was lined up for straight the electricity was supplied to the side. The two other's had to be tightened and the last one is crap the wires are in the wrong places... Way to go China.
