r8247 point decoder

[victorrichard]

My r8247 point decoder stops working if a train short circuits over a set of points. All 4 points on the decoder stop working. I then have to disconnect all the wires and remove from the board to reprogramme. This only happens on the same decoder all the

 

others decoders still work ok even if a train short circuits on another set of points. Please help

This is not supposed to happen, although clearly it does from time to time. If less then a year old, return to the shop or Hornby for replacement.

Hi,

Have a look at this thread from the DCC Forum: "R8247 Acc Decoder Stopped Working".

Maybe a Bus Filter is what you need.

Buying a resistor and capacitor will be a lot cheaper then £8 if you can solder too.
