@chrissaf hi Chris, just an update; albeit almost 12 months old. These random point moves were causing me many a headache.. After many point motor , wire , switch and even control system changes I went back to the beginning and re read my many books on Dcc control . it would appear that the solution was staring me in the face but I didn’t think it applied to my layout . I had read on many occasions about bus wire filters, I should say “misread”. As the point was only 10ft. Away from my control panel I did think I needed them … But of course it has nothing to do with the distance of the malfunctioning point from the control panel , but the overall length of the bus wires , which in my case is just under 50 feet. Needless to say I have fitted the capacitor and resistor across both ends of the bus wires and since then no phantom changes.. It just goes to show how easily misunderstanding what we read can back fire. .. Again thanks for your input
