Thanks for all the help, particularly the last two comments which rally make sense. I think that what you're saying is that trying to send power from the decoder to the live electrofrog runs a high risk of shorting because of the timing of the switching vs the timing of the blade movement. Do I read that the only solution is to do without the frog polarity wiring and really on switch blade contact? If so, any hints on how to improve this contact.....some of my points seem very prone to pore contact. Thanks, Ian

Thanks Paul, yes, have used insulated rail joints throughout on all frogs, I even sent a plan to Peco technical bureau who came back with detailed advice too. My understanding too was that there was no need to modify points. As I say no problem with DCC power to tracks which I assume means insulated joiners are in right places??? Ian

I am currently wiring my n gauge layout on which I've used Peco streamline Code 55 track with electrofrog points and Cobalt ADS 2fx decoders. Wiring the power supply to track went well. Everything worked with no shorts so I believe that I've placed insulating connectors and track feeds in the right places. The point operation also works well too....all the points operate as planned again with no problems shorting. HOWEVER, for each of the points I have soldered a drop wire from the frog and connected it to the central input on the frog power section of the decoder. I have then run a wire from each of the live and return terminals on the decoder.....but when I attach them to the bus wire I get a short.....sometimes! There seems no rhyme nor reason to why this happens sometimes and not at others, and this is driving me nuts. Any obvious answers? Have I done anything fundamentally wrong? Ian
