Thanks Dave, No I have never had any problems with any decoders, except for two or three I toasted when I started converting to dcc. The decoder I was using was a Gaugemaster 4 function 1.8 amp . It still works with the lights, and forward movement , but no reverse. I can see a small burn mark on the decoder. I checked all the wiring, and all is as it should be. I was having a bit of trouble trying to get the motor to turn, and when I checked it, there was also burn marks on that . As you know it is only a small motor on the 0-6-0 shunter, so I may have overloaded the whole lot. I will get a new motor and decoder and try again. The motor I am looking for is a Hornby DCC ready 0-6-0 motor assembly (modified),x8809m but they can not be got anywhere at the moment. I will watch ebay.
Thanks,
Controller.
