The problem lies in the fact that the repeater тупливает, and not one, but several, in different ways, at different times, in different place, on the screenshot shows that the repeater works, although to do this he must not, the power source is there. Such a phenomenon I have started with the picture 13w06a, previously, this was not respectively (picture 1), immediately arises because of this error with rails (unfortunately the picture show can not, because the time of day has changed, and the whole system works from the sensor sunlight), such a scheme (figure 2).
