All of my points have suddenly stopped working!! The CDU output is fine, I tried another one just to be absolutely sure. 5 of the points are electro frog using Seep point motors and Gaugemaster Autofrog polarity switching and 3 are Insulfrog using Peco surface mount motors. Locos operate normally on all parts of the layout, switching the points manually. I was laying some ballast, tapping the track with a spoon to bed the ballast down, without realising that power was switched on. Could the short circuit have damaged all the point motors???? If not then I have no clue where the problem is. All the points are operated by toggle switches, could all the switches have burnt out? The layout is DCC using Gaugemaster Prodigy Express DCC01 control.
