I bought two sets of touch sensitive under cabinet kitchen light set put them in but one set keeps flashing then stops all together I've replaced the transformer and the touch switch but the wires in the six port connector, when you move the wires there the light go out two which one you touch . Now the lights will not work with this transformer. Can a loose wire from the ligtht two the six port connector keep blowing up the transformer.

Let me guess, is this a Hampton Bay lighting kit? If so return it and buy something else.

If not seems you need to return it anyway. Sounds like the wires in the plug are not making contact properly. I do not believe this is causing a problem with the transformer, unless the wires in the plug are shorting out.
